LHC will only operate at half power to try to detect problems earlier

The Large Hadron Collider may usher in a new era of particle physics as the world's most powerful particle accelerator.  However, the LHC has also been the victim of numerous delays, ever since its launch last September failed. 

At launch an electrical fault between two of the magnets reportedly caused an arc of electricity, which in turn triggered a helium leak and explosion.  As a result, the proton tube was contaminated with soot, and the magnets were broken off from their mountings.  Months of repairs revealed more leaks in the vacuum of the insulating layer surrounding the proton tube.

Now the European Center for Nuclear Research, or CERN has declared that the repairs are done.  States CERN in a press release, "[Tests] will initially run at an energy of 3.5 TeV per beam when it starts up in November this year.  This news comes after all tests on the machine's high-current electrical connections were completed last week [the week of July 27], indicating that no further repairs are necessary for safe running."

Still, the restart represents caution on CERN's part -- 3.5 TeV is only half of the beam's full intended operational power.  States CERN Director General Rolf Heuer, "We've selected 3.5 TeV to start because it allows the LHC operators to gain experience [with] running the machine safely while opening up a new discovery region for the experiments."

There remain concerns about whether the device is capable of running at full power.  Describes CERN:

Following the incident of [Sept. 19, 2008] that brought the LHC to a standstill [due to a faulty magnet connection], testing has focused on the 10,000 high-current superconducting electrical connections like the one that led to the fault. These consist of two parts: the superconductor itself, and a copper stabilizer that carries the current in case the superconductor warms up and stops superconducting, a so-called quench. In their normal superconducting state, there is negligible electrical resistance across these connections, but in a small number of cases abnormally high resistances have been found in the superconductor. These have been repaired. However, there remain a number of cases where the resistance in the copper stabilizer connections is higher than it should be for running at full energy.

However, CERN also says that it has tested and repaired a large number of these faulty copper connections.  It says that the final two sectors it tested revealed no abnormalities.  Nonetheless, after all the headaches, it plans to throttle up the 17-mile long accelerator loop slowly, just in case there's still undetected problems.

Any black hole created would probably go unnoticed. Its event horizon would be so small and gravitationally negligible that it would be nigh miraculous if it ever sucked in just a single atom before the sun burns out of hydrogen.

I remember reading an article about a scientist who working on the problem of how to deal with a black hole if it was actually created in the LHC.

His suggestion was that firing charged particles (electrons probably) into it would make it negatively charged, then surround it in a similarly negatively charged enclosure to prevent it from touching the sides. Then you fire it off into space.

Assuming you know where exactly the black minihole is. Hitting such a small thing with particle beam must be either

A) hard like hell - then its ok, cause the hole is not interacting with the environment (much)
B) easy - then were doomed, cause it surely has started to suck up matter already, is growing and it probably is too late to act.

Fortunately, the very theory that predicts the possibility (not certainty) of a black hole forming in the LHC also predicts that the black hole would instantly evaporate in a few femtoseconds.

If you can possibly interact with a charged particle inside a black hole via electromagnetic force, then you've violated the whole event horizon principle.

Curious, even, that gravity itself escapes the event horizon. I don't know how this could be explained by any gravity-transmitting particle (graviton?) theory.

But it wouldn't need anywhere near the mass of the Earth, considering how much closer the black hole in your vacuum cleaner would be to the object than the centre of the Earth. It's like a small magnet that's really close has a bigger effect than a huge magnet many many miles away.

Anyway, the black hole would be constantly sucking in the atmosphere around it, creating a vaccum, and you'd be cleaning the old-fashioned way, with good ol' static pressure pushing dirt down the tube.

Yes, it's still ridiculous...

The energy is equivalent to 120lb of TNT during an collision. Not all of the energy is inserted into the accelerating particles. What really goes wrong will not be the black hole, because the particles are getting so big during acceleration that the black hole will never be exposed.
The LHC puts in magnetic energy and what it gets out is the magnetic particles. You are what you eat basically.

I put it in a simple term so people can understand. The mass is accelerated to near the speed of light, E=mC^2. The energy is converted to mass, it is like an orange with a hyper thick skin. During collision, some of the orange skins will be separated from the orange and landed onto the detectors.
If the particles are not magnetic then the particles should not be responding to the magnetic fields. Are you implying that the Maxwell's equation is wrong.
LHC is still in the religious stage.

Now the binding energy inside an atom uses the mass-energy equivelance equation you quoted... but in terms of the objects kinetic energy e=mc^2 has nothing to do with it.

About that magnetism thing. A particle can be magnetic only in that it has an electric charge distribution across itself and it is spinning. Iron atoms are all little magnets because the atom spins and the electrons around it do not form an even charge distribution across it. At any given time there may be more charge at one side of the atom than the other. Wan der waals bonds in metals uses this principle IIRC. Anyway, magnetism is created by the motion of an electric charge, nothing more and nothing less. Charged particles experience a force due to a magnetic field - directly proportional to their velocity - because when they move, they actually create their own magnetic field which interacts with the one that is, apparantly, impartng force on the charged particle.

More to the point is how little an amount of energy there actually is in this beam?

Tera-electron volts sounds huge, but at electron volt is 1.6e-19 joules of energy. A 14TeV (i.e. 14x10^12) collision, the biggest this thing is supposed to be able produce is around 10^-6 joules. So a collision in the LHC can produce enough energy to power a 100w lightbulb for.... one hundred millionth of a second .

Or, more pertinantly, you'd have to 'save up' the energy in these collisions for 11,400 years. Eleven thousand four hundred years to get one hours worth of use out of a 100w light bulb.

LOL, AND PEOPLE THINK THE WORLD IS GOING TO END ROFLMAO!!!!

Cosnic Rays in the wild hit up to 10^20th electron Volts; 10 with 20 zeroes behind it.

The Tevatron, outside of Chicago at Fermi Labs, hits around 10x12th eV (1 TeV) while the LHC, maxed out in it's launch configuration, is 7 TeV or 7x10^12 eV...

Last time I looked out the window, the earth hasn't been swallowed...

So if the LHC can generate black holes, they've been being generated over your head for the past few billion years or so.

I've got better things to worry about.

If the repairs are complete, why wait until November. Lets fire this thing up now so they have even more time to test it before their "European" Winter vacation. :-|

Scientists around the world are waiting for the data, and willing to accept a headcrab or two in the name of science. After all, only one or two are acceptable anomalies in the name of Science. ;)

Seriously though, if it really is complete, what is the point in waiting any further. They only have a limited amount of time before winter comes and the inevitable shutdown. I think a whole year of setbacks is enough - that is, if it really has been completely repaired.

In the above link, they mention it will take two full months to initiate repairs, which, during that time, they would warm the collider and then cool it back down again.

So, the two months is bunk. I would wager it takes 3-4 weeks to cool the thing. That is 1 1/2 months of it doing nothing.

When you are dealing with extreme temperatures it doesn't make much difference if it's winter or summer on the surface (they operate below ground). Actually I've read that they do not operate during winter mainly due to electricity being a lot more expensive (>double).

In the off chance that you are not just being daffy:

The Mayan's base-20 math system was capable of calculating out well beyond December, 2012. There were numerous times where dates were found far beyond the scope of the supposed 13.0.0.0.0 doomsday. These included a date roughly 41,341,050x10^21 in the future.

In reality, it is almost certainly a case of parsimony where the Mayan mathematicians simply didn't see a reason to include the leading zero on their date. Think about it this way, the time span from 1.0.0.0.0 to 13.0.0.0.0 would have taken them from August 3114 BC to December 2012 AD. It is only logical to think that, had their society managed to survive to 2012, they would simply roll over to the next significant digit(or 1.0.0.0.0.0).

The dissemination of the 2012 doomsday message has been a matter of commercial success for many people looking to cash in on this clever bit of fiction (I'm looking at you New Age!). More likely than not, we'll see nothing but a rise in 2012 stupidity as the day grows near and passes just as Y2K did and numerous other predicted end days.

It will come, and it will pass and those who capitalized on fear will count their royalty cheques and move on.

The Mayans were orders of magnitude more primitive than the Spaniards.

Their mathematics was almost childishly trivial compared to the greeks of thousands of years earlier. The Spaniards had universities, embassies, factories, metallurgy, pack animals, chemists, global trade routes, small arms and artillery, the list goes on.

The Mayans were just as intelligent as anyone else, but were handicapped by being out in the middle of nowhere, away from the exchange of ideas in Europe, North Africa and Asia.

It was a shame they were run over by the Spaniards, although their civilization had been in decline for hundreds of years before the Spanish arrived.

I'm as impatient as anyone...I'll be checking their cooling status on a daily basis. Here's the page to do this; they have a color diagram so you know approx. how warm/cold each area is:

That must be some damn impressive impatience you got there if youre gonna check it every day, considering they havent updated that diagram in 3 weeks...


Let's hope it delivers the goods.

After all this there better be some awesome discoveries.

If this thing doesn't deliver it will be the biggest scientific dissapointment in recent history, or at least the most expensive.

I expect this thing to build a gravity drive for my car by the year 2020... DAMMIT! ;)


Not complete

The title to this article is wrong. Repairs are not complete, the press release is about the planned November Start-up at half power.

http://cdsweb.cern.ch/journal/article?issue=30/200... :
quote:
[...]during the past week vacuum leaks have been found in two "cold" sectors of the LHC. The leaks were found in Sectors 8-1 and 2-3 while they were being prepared for the electrical tests on the copper stabilizers at around 80 K. In both cases the leak is at one end of the sector, where the electrical feedbox, DFBA, joins Q7, the final magnet in the sector.

Unfortunately, the repair necessitates a partial warm-up of both sectors. This involves the end sub-sector being warmed to room temperature, while the adjacent sub-sector "floats" in temperature and the remainder of the sector is kept at 80 K. As the leak is from the helium circuit to the insulating vacuum, the repair work will have no impact on the vacuum in the beam pipe. However the intervention will have an impact on the schedule for the restart. It is now foreseen that the LHC will be closed and ready for beam injection by mid-November.




Science today is a joke

Forget this expensive piece of shit ever working. Go back to fabricating global warming mythologies and not curing diseases, science.

Stupidity and climate change denial so often find a home in the same brain.

funny how people predict the end of age in almost every new thing, when we are allready in control of the button to do just that.

Its never more than "a push of the big red button away anyways".

With the threat of the SEC investigations on covert bank accounts the swiss bankers are looking for a new place where to hide mafia money...
Another way they are attempting is stuffing money on catamarans on Geneva's lake and transporting it out of the borders with helicopters.
These foxy neutral neutrons!
