Collider's restart delayed

Posted: Monday, February 09, 2009 4:57 PM by Alan Boyle


CERN
Workers prepare to lower a magnet into the Large Hadron Collider's tunnel.

The restart of the world's biggest particle-smasher is being postponed until late September at the earliest, to allow for the installation of a safety system that would have reduced the amount of damage done during last year's electrical breakdown.

In today's announcement of the additional delay, Europe's CERN physics research center said the Large Hadron Collider should produce its first proton collisions in late October and its first science results next year.

The LHC, housed in a 17-mile-wide ring of underground tunnels on the French-Swiss border, is designed to produce the most powerful subatomic smashups ever engineered by scientists (although cosmic rays in space are thought to reach higher energies).

The $10 billion international effort is expected to shed new light on a whole range of cosmic questions: What is dark matter made of? Why do some particles have mass while others don't? What was the universe like just after the big bang? Does space have extra dimensions we haven't yet detected? Scientists say the machine might even create ultramicroscopic black holes - which they insist would blip back out of existence without harming anything.

There may be no danger of a black-hole blow-up, but a more down-to-earth problem forced a shutdown of the collider shortly after its widely publicized startup last September: A bad electrical splice in the collider ring caused a sudden loss of helium coolant, resulting in major damage to some of the ring's magnets.

CERN, which is making an estimated $29 million worth of repairs during the months of downtime, had hoped that the magnet ring would be cooled down enough to restart the proton beams in early July. But today's announcement said engineers will need some extra time to install a more sensitive system to monitor the electrical resistance in the splices, as well as new pressure-relief valves and other safety measures.

To make up for the lost time, CERN will add extra weeks to the collider's work schedule after the restart. CERN customarily shuts down collider operations for several months during the winter, but toward the end of this year, there'll be only a "short technical stop" for the Christmas season. Except for that short break, the LHC will run straight through to the autumn of 2010, CERN said.

"The schedule we have now is without a doubt the best for the LHC and for the physicists waiting for data," CERN Director General Rolf Heuer said in today's status report. "It is cautious, ensuring that all the necessary work is done on the LHC before we start up, yet it allows physics research to begin this year."

I don't understand why we NEED to know what dark matter is made of, or if space has extra dimensions we haven't detected yet. Couldn't the money being used for this project be put to better use? If scientists can figure out how to build a particle smasher, can't they figure out how to make cars run on water or air? Or, find cures for diseases?
Let me get this right. They're going to make a black hole with this thing and that's it, right? How many millions did it take to make this machine to do one thing and then what, take it apart? Sounds like a money maker for a few people with the downside that the money might not be worth much if we're crushed in a black hole.
regina: if the scientist discover the things that they think that they will, the findings may not have an immediate effect on your daily life. but they will have long term scientific implications. how we came to be, what happened when time started and how we might be able to harness the power of "dark matter"

tom: no they arent going to make a black hole and then tear it down. what kind of question is that. there is no danger from these black holes either. read up on things before you comment on them.
This is basic scientific research which we cannot afford not to do. While it may seem senseless now we can never know what it may lead to. Studying mold on a orange at first sight is senseless but it led to the discovery of penicllin which has proven extremely useful. Compared to the trillion dollars to bail out U. S. banks it is a bargain.
The ignorance being displayed by the comments here is astounding. There is no way to make a car run on water or air as neither has the rigt energy content.
Second, they are not creating black holes. Third, the undrstanding of nature at a fundamental levls is a proven way to develop new technologies and prosperity. Ever heard of elecricity?
I am sick of, "Why are we wasting money on this," arguments. 300 years ago when scientists were messing around with magnetic rocks and static electricity I could have made the same argument by saying, "Why are you guys wasting time on electricity? It has no practical application." The most benificial scientific advances have been made by people tinkering with something that seemed completely useless at the time. More to the point, partical colliders have already givin us directly or indirectly, the MRI(Magnetic Resaonance Imaging), the PET scan(Positron Emmission Tomography), CAT scans, Radiation Cancer treatment, Industrial Superconductors, Modern Computers, The Internet, Food Sterilization, Scanning of ships and containers, and others to numerous to list here.
What do you think caused the "big bang" in the first place? a bunch of dweebs trying to create a big bang :)
not to worry no one will ever know about it, happens in less than a milisecond......
the technological advantages that the LHC could yield are endless... many technologies that we take for granted once came from way out there ideas... The principles behind Magnetic Resonance Imaging (MRI)  emerged form particle accelerator research for example.   While the fundamental principles that we hope to discover at the LHC may seem pointless and irrelevant, the distilled technologies from the LHC results could change the world as we know it.
Basic research has lead to many useful things. You never know in advance, it may be just another black hole for $. At any rate enlightened minds want to know, the rest just want to curl up in safety knowing there is nothing new to be discovered (of value.) Good thing there were people like C. Columbus, lots of people at the time thought the earth was flat. Like people today think the universe is only 6,000 years old, enlightenment!
Every aspect of our daily lives has been impacted and dramatically improved by technology that is a direct spin-off of research done in the fields of Astronomy and Physics. ( and others) We need more pure scientific research, not less.
Well, it is within the  memory of man that officially, the earth was flat and no one thought it important to prove it otherwise. Also that  the iron plow would poison the soil and the U S midwest was an unusable wasteland.  If money had not been spent to prove those sacred precepts and certain knowledge to be false, and that much good was derived from such proof, where would the human condition be today?

While it isn't  easy for most of us to understand the worth of understanding the way the universe is constructed, many do, and are confident that much good will be derived from it. As I have seen such investigations pay off in my lifetime, I endorse  this work, wholeheartedly.
The study of particle physics has yielded many medical benefits such as medical diagnosis and treatment including the treatment of cancer patients.  They help us to understand the nature of the universe which understanding aids us in all kinds of technological advances that are now indispensible to us (such as the superconductor).  Without that understanding to build on you may never see a viable, clean alternative to the fossil fuel powered car or the medical cures we seek.  Future technology hinges on us understanding more about the universe we live in and understanding comes through scientific investigation. Not to mention that so many scientific discoveries that have benefited us have been discovered while investigation something completely different.

The following website explains some of the many benefits that have come through a better understanding of particle physics.

I think it's very interesting.  But then, I've studied the history of science and technology.  I've also read many books describing physics theories.  Recently I finished Einstein by Walter Isaacson.  The machine will be used for decades if at all possible.  I'm not even aware of a tenth of the things it will be used to study, but there are many.
Will the ability to create a black hole theoretically dwarf the power of an atom bomb?  I hope not, for humankinds sake.  How can you play around with such dangerous things and assume we are safe.  As long as there is unkown aspects of these phenomenon, it remains dangerous.
This is fundamental research. Your television wouldn't work without it, and neither would some semi conductors that are used in many electronic apliances. What will come out of this research is not predictable, but one thing is certain: it will be something BIG, maybe something that has the potential to turn our economies or even our societies around just like television or the computer did. In that light, 4 or 5 billion dollars is nothing. Just look at what IBM has been investing over the years.
besides, have you forgotten that the internet was invented by two people at the cern? Their names are tim berners-lee and robert calliau. That invention alone paid for the investments in a new particle accellerator. looking forward is the right way to go!!
Would you PLEASE at least do the MINIMUM research related to this field of particle physics before making ignorant comments?  So you think that the field of science and technology should simply sit still and never move forward from this point?  What if people like yourselves were in charge of all this?  Well then we'd still be using vacuum tubes and rotary dial phones.  Do you have any idea the insane amount of money that went into the development of the transistor or microchip?  Hmm, did either of those change our world for the better at all? Gee, I wonder, it's not like satellites or computers are of much use huh?
Projects like these are necessary if we wish to advance our technological capabilities.  We NEED to know things about dark matter and extra dimensions to get answers about questions which never occured to us.  Doing these experiments will eventually lead us to things like "how to make cars run on water or air".  While it might not seem to be a practical use of money to some, the results will benefit everyone in the long term.
Are we really going to allow these fanatics to create a machine that has the power to destroy all of Gods creation? These sorts of sacrilegious doomsday machines m should not be tolerated.
No, it's not just about making a miniature black hole.  There are other experiments being done.  It doesn't do just one thing.  The article only covered one thing.  There are a raft of scientists all looking at different aspects of the particle collisions.  The collider is a good thing.  We'll learn a lot about astrophysics.
The particle colider is very important then most people consider. If they would take the time to understand the information that is gained, they would have a much greater respect for this type of science. Not to mention the fact that people are not going to pay billions of dollars to make something that is not "worth it".
We need this machine to prove that the moon is NOT made of green cheese. Time to put that well believed factoid to rest!
Regina, Tom,

Not at the front of the line when they handed out imagination, huh? Think beyond your small lives and try to see a bigger picture. Not all knowledge is useful in itself, but if it leads to something bigger and better ...
And anyway, this isn't your money or the US Government's money, it's not your tax dollars, so get off your holier than though attitudes.
Why do we need to drive cars anywhere when we can walk? Why do we need the Internet when we can talk?
Why use a whiteboard when we have chalk? (forced rhyme...)

There is a lot that could be discovered with this machine...
They're betting the entire planet and six billion peoples lives that a potential black hole will not run away and they can't even keep the damned thing running.
I don't know why but I sincerely feel that this is an important step for mankind.   With this machine functioning maybe we are going where no man has gone before.   I hope that it is not the case where we are going where no man should go.   We are counting on these scientists to use their best judgment.  

I would like someone to answer the question how small must a black hole be to be of no danger to us all?  We have been safe from black holes because they are so far away.   The ones we may be producing are in our back yard.  If more than one black hole is created can they merge?  Would that make a difference?
People...educate yourselves about the science behind this and other machines like it.  If you've ever known someone who's received radiation therapy, you can thank machines like this.  If scientist do figure out how to make cars run on something other than oil, it will be precisely these kinds of experiments that will lead the way.  Basic resarch is the engine of society's evolution.  Of course,  if all this seems like too much work, we can simply sit back, watch TV all day and let our friends in China do the science.  I'm sure they'll share the results with us once we learn how to speak chinese.
Judging by the comments here, small minds with small thoughts are not in short supply. When mankind stops exploring and trying to understand the mysteries of the universe, we will return to the dark ages, where ignorance and superstition prevailed. In the past, great minds explored the universe with their powers of introspection, imagination, analytical ability and logical deductive reasoning. These days, petty minds count nickels and dimes and pennies, seemingly lacking even a basic education of scientific fundamentals, never mind having the capacity to think critically. It's a sad day that America has come to this.
Cure for diseases? Sure, like debilitating technical myopia.
I'm actually a bit bummed out that I have to wait another year before I hear anything cool coming from the LHC.  I'm not really a student of science, but I do watch and read a lot of material on space, time, and matter.
On another note, I am rather tired of seeing the complaints of others on this post about what the LHC has to offer.  First, it's human nature to be curious about things.  Second, biproducts of the research or methods used in attaining this knowledge results in technological improvements that benefit everyone.  Ever heard of "The World Wide Web"?  Contrary to belief, Al Gore did not invent it.  It was a biproduct from a previous particle accelerator, at the CERN Lab on the France/Switzerland border, when scientists needed to communicate data more efficiently with each other.  Aside from that, other technologies arose from the use of particle accelerators, such as cell phones.
All in all, it's a good thing we're trying to understand the universe.  It just makes things better for all of us!!
Regina,  I'd agree with you, but the reality is that car companies own politicians.  If some other company of scientists came up with a better car, the car companies would bog that company down in litigation until it wasn't cost effective to produce the car anymore.  As much as we'd all like to believe that its all about protective the Earth, its not.  Its about money.

Tom.  Did you read the article?  Its going to make MAYBE a few small black holes, but those aren't really the focus of the experiment.  The analysis of matter leads us to fundamental new ideas or equations that could potentially allow us to colonize other planets, or make space travel possible and time effective.  Black holes with the destructive power to crush the Earth are born only of immense amounts of matter (i.e - stars) collapsing in on itself.  Single photons colliding MIGHT create microscopic black holes that wouldn't be able to sustain themselves, much less envelope the entire Earth.
Oh wow...  I just read the first two read comments from Tom and Regina, and it makes me sad.

Understanding what dark matter is has extreme implications on future technologies including, but not limited to, polution free generation of energy, gravity control, and the ultimate fate of the universe, where the human race currently resides and keeps all its stuff.

No need to fear any black holes generated by this puny little device.  Keep in mind the only black holes we really have to worry about are those that are generated by stars that are 10 times the mass of our sun or greater, and that the energy used in the LHC is approximately 10 to -1,000,000,000 amount of the energy required to produce a black hole that would 'last' long enough to do have any significant impact on the planet.

"IF", and it's still an extremely HUGE "IF", a black hole is create, the 'size' of the black hole is indicated as being 'microscopic', which in of itself is a gross over estimation of the 'size' of the black hole.  The black hole's 'size' would be atomic, or maybe not even that large, but sub-atomic.

I think what scientists have done a piss poor job of explaining is that the 'size' of the black hole is area of gravitic influence.  If I understand how all this works, the black hole is a singularity, a singularity is a 'point' in space, and in speaking of blackholes it's a point in space where gravity is warping space back in on itself.  You do this at the sub-atomic, atomic, or 'microscopic' level in a vacuum, and there's not going to be enough mass available to 'feed' the black hole to keep it from completely evaporating itself through Hawking radiation to become an issue.

IE:  It's like being worried about a kid creating a fusion bomb using the scrapings from his glow in the dark watch dial.  There's just not enough there, nor will there ever be enough there, to worry about.

Deep breaths, relax people.

Science drives technology, technology drives innovation, innovation results in interesting applications, interesting applications are potential products, potential products marketed well drive demand, demand drives business opportunities and markets.

It used to be believed any human being attaining a physical speed greater than 35 miles per hour would die.

If scientists let the limit stay at that rate, it would take days/weeks to cross the north american continent, weeks/months for oceanic travel, and life as we currently know it, would not at all be possible.
LHC for life, son!
Everything around us has come about because of the understanding of atoms. With the correct results we may someday make our cars run on water alone.
The collider will answer some of the most pressing questions regarding space travel and matter composition. I cannot think of a better way to spend money and science should have more funding. That way people will then know why the collider is so important to science and not insist on using the small amount of funding to battle other problems.
Facinating and a bit scary.  I am curious if we may ever find the bridge between Newtonian Theory and Sub-atomic particle theory.  We struggle understanding Newtons responses as we build the space station and bandage economies. We have the Hadron Collider to search the sub-atomic particle end-of-the-spectrum to attempt to grasp that we are made up of nothing at all.  Is this a candle burning at both ends?  We are seeing how a time of differentiation is simply leading us back into unification.  Think I'll go wind up my pendulum clock.
Regina,

You also may not understand the incredible amount of knowledge about material and energy physics that went into creating the devices you used to create and send your message.  TO continue our advances in technology and the sciences we need to know as much as possible about the resources that are available in our universe.
Too bad so many superstitious savages can't figure out that we need tools and knowledge to solve problems.  One huge problem is that we are running out of energy and need a way to produce it economically.  A tool like this may show us the way, for example.
Regina, I'm sorry you don't understand the scientific value of the collider, and the immense benefits to humanity from the knowledge that could be gained from it. Maybe you should consider that your lack of knowledge is the problem, and not the value of the collider.  A little education in science is a wonderfully useful thing, and since I live near you, I suspect the problem is with your schooling. Education shouldn't end with high school graduation, though, so I encourage you to pick up a basic science text and give it a try.  If you don't know, scientists of different specialties ARE working on cures for diseases, and engineers are working with cars.  Concerning cars however, If you don't understand why we don't have a vehicle that gets better gas mileage or is powered by an alternative fuel, maybe you should explore the politics of the oil lobby.

Tom, your worry about being sucked into a black hole should be way down on your list of threats to yourself. The scientists involved have discussed that issue and put it to rest.  Maybe you should look into what's in your food and water.  
Crushed - not, ripped apart, maybe.
I wonder if all the so-called "problems" the Large Hadron Collider is "experiencing" actually are definitive proof of the ability of the Heisenberg Uncertainty Principle to operate across vast distances not only of space but also of time?

Is it possible that some event in the future actually is affecting the past based on the general rule that the only way to prevent it from happening--hence from violating the key prohibition of the Heisenberg Uncertainty Principle-is to alter what for it is the past but for us is the present?

Could it be that so long as a certain as yet unidentified "experiment" continues to be either on the books or in the mind of someone, the Large Hadron Collider never will start working, instead continuing to experience a virtual festival of strange and unusual singularities until eventually someone, perhaps a clerk in a patent office somewhere in another dimension, connects the dots and determines that all the problems can be solved by adding highly reflective mirrors to the walls of the lobby?

I have no idea, but it certainly is beginning to appear that something mysterious is happening, especially considering the possibility that the Large Hadron Collider actually has been fully operational for a long time but the results of the so-called "experiments" are so startling that our leaders have decided that it is best if we simply do not know what happened . . .

That this appears to be a bit beyond strange makes it all the more likely, really, because one of the fundamental requirements of all illusions is that they only work so long as just a handful of people know the truth . . .

Thanks!
Hey Regina, research on how things work is what leads to cures for diseases and better ways to run cars. For example, why should we be limited to running cars on perfectly good water or air when we could use the zero point energy of empty space to power nanomachines that could cure diseases or provide more effective transportation? And if we can prove and use other dimensions... who knows what we could do? The Large Hadron Collider is just one of those research tools that can help expand our options in ways we can't yet envision.
Are you kidding me?  So I guess now all research that does not end in a new version of the "Sham-Wow" is just a waste?  The two of you above (Regina and Tom) really need to get a clue! This "thing" is one of the most important scientific tools ever built.  Yes, it does come with a price. No, it can not be built for free by scientists on their own time over the weekend. I am so sick of science being attacked for every dollar they spend for the sake of discovery.  These same people think that everything just "is", that some how it took nothing to create the things we have today.  As an example the discoveries made that stem from the research and development of the U.S. space program reaches into every persons daily lives.  Scientists are not wizards, nor are they prophets; every question has an answer but it takes research, experimentation, and of course money to fund the research and experimentation process.  Not every program has a clear cut beneficiary, not every experiment will be successful, but the process is what we all depend on to advance the human race forward. Even though you may not personally find value in what these scientists are trying to achieve, I am asking you to try and imagine what your life would be like with out your "blackberries", "iphones", "laptops", and all the other daily convieniences that were born from research and scientific discovery.  Just in case your wondering... no, your iphone does not run on magic! Instead of asking why the money wasnt used for something else, you should be asking why arent we putting more money into scientific research? The enlightened life is the only one worth living.  I think you two need to work on it!
They need to understand dark matter for the same reason we needed to understand nuclear fission, combustion, electricity, how to communicate via written language, etc. Without going into a science lesson... in theory the use of dark matter could be a tremendous source of energy. It could also if able to be controlled eliminate matter and solve our nuclear waste and other problems. Kind of like having a bottomless garbage can. Lots we can only speculate about until we know and understand. Ofcourse that is assuming that dark matter even exists. Miniature black holes have tons of their own uses as well.. If only we can learn and understand. I am just glad that those who scoffed at and wanted to stop science in the past didn't succeed.
Are you kidding me?  This piece of junk will never work!  It's only been job security for a bunch of morons who have people fooled into thinking that "they" (the scientists involved) are smart and are really doing something productive.It's a waste of time and money cause the next time they start it up it will fail again.  They don't know what they're doing.
Regina and Tom - I appreciate that in these tough times, you have fears and reservations about funding cutting-edge scientific research. The best thing both of you can do to help our economy is very simple. Continue to do your jobs and let the thinkers do theirs.
No Tom, you did not get it right. You did't even allow for the little bit that the article stated IE expected to shed light on a whole range of cosmic questions. If we always credit your style of negativity, there will never be any scientific discoveries, therefore we may as well just stop teaching science at all. Think of how much that will save.  
Pure research is never a waste of money.  A greater understanding of our world and universe is to be gained from the LHC and other such facilities.  The applied technologies will follow.  

Anyone who has ever had a PET (positron emission temography) scan owes it to the world of particle physics.  To name just one application.
due to population growth, the suns' life span and the earth's depleting resourses, the time to invest in our future is now, traveling at the speed of light will most certainly be a necessity in a decade or two, understanding the pitfalls of intergalatic travel before hand is not unreasonable, besides money is only numbers, space travel is endless hope
Regina -> understanding what makes up the universe is pretty important dont you think? Electrons are small, they brought us electricity. The whole point is to "look under the hood" and what everything is made of so we can better understand and master it. Knowledge is power.

Tom... No. Its not the point. Wikipedia might be a good start mate.
While I agree that the LHC is comsuming a lot of money, and likely will for some time, we cannot abandon science and our quest and thirst for knowledge.

As for cars running on water and air ... these are both technologies that are happening right now, in our time. Fuel cells will change the way we think about mobile propulsion and the air car? The technology, concept and prototypes are already on the road from a company named Motor Development International http://www.mdi.lu/english/

The future isn't just coming ... it's here and happening around us every day.
