Large Hadron Collider team announces beginning of restart

Apr 08, 2014 by Bob Yirka report

(Phys.org) —The team of scientists working at CERN's Large Hadron Collider (LHC) facility has reported to the press that the process of restarting the massive experimental mechanism has begun—though it won't finish until sometime next year. The world's most complicated system of machines will have to be restarted in pieces to ensure that each is operating properly before the next can be brought online.

Though proving the existence of the Higgs boson was a major goal, and achieving it garnered a lot of headlines, the facility at CERN has made progress in other areas as well—the creation of quark–gluon plasma back in 2011, is but one example. Now the facility is in the process of an upgrade, which has been in the planning stages for several years and will include upgrades to several pieces and parts of the facility that support the LHC as well as the main accelerator itself. The team recognized that the facility had begun to suffer from diminishing returns and that many parts could be improved due to the development of new technology and improvements on old ways of doing things. Thus, this past February the LHC, along with other parts and accelerators that feed it, was shut down. The retooling has been forecast to total approximately $4.4 billion dollars.

Thus far, the team has successfully restarted the part they call the source—the piece of equipment responsible for stripping electrons off of for use in producing . Next up the team plans to fire up Linac2, an accelerator whose job it is to give protons their initial push. After that a booster will be started that will be used to push the protons even faster. For the LHC to be used in its proper context, it must receive protons that are already moving exceedingly fast.

Team members have made much of the complete upgrade to the control system for the LHC—the part that integrates all of the systems and which of course will be central to a successful reboot. They should know early on if there are any problems. In addition to swapping out parts for new and improved technology, technicians will also be replacing worn cables or other minor but necessary components. If all goes well, the LHC should be ready and back in business sometime early next year. Projects in the pipeline include: ALICE, CMS, ATLAS and LHCb.

Such a pity the Americans would prefer to spend $4.4Bn on obsolete militarism.

Try closer to a $1 trillion a year. The real pity is that we have been forced to spend so much to protect our parasite European "friends" from each other for the last century. And now we are spending just as much trying to emulate the socialist society they constructed with the extra money they had available because they depended on us for their defense for the last 70 years.

dan42day . Ignorant comes to mind, 'depend on us for their defense'. For a start the majority of wars are started or escalated by America, no doubt for some sad military gain, and secondly do you honestly believe any country depends or even wants America to get involved. The world would do perfectly fine without American forces and a huge amount of lives would be saved. You do realise that this small world is made up of a lot of other countries, many of which are far Superior to America, not only financially but in culture, design and intelligence. America obviously has a lot going for itself but there's a definite power shift on the go from 'West' to 'East'.
Maybe you should go travel the world a bit dan42day and see for yourself.

Like to see it running at full power.....

I wonder what would happen if you stuck your hand in the beam?

"Oooooooo?"

@dan42day, pull your head out of the sand mate!!!
You seem to have forgotten that most of the tech the US uses is from Europe!!!
Also, America did not "help" Europe for free. Britain only finished paying off its WW2 debt in the 1990's, some 50 years after the end of the war FFS. America effectively enslaved many European nations via economic control via WW2 debts.
Also, who did America sell weapons to during WW2?? Both sides, thats right, BOTH SIDES!!!
I would go on, but you're obviously an ignorant American who thinks the USA runs the world.

The rest of the world relies on the greatest economy that has ever existed in human history, the USA Capitalist Economy,.... the USA dollar runs the global market, you halfwit. Other countries have greatly benefited merely by existing in the USA's wake.

In terms of war, the USA has been only a force for good against oppression, at it's emense personal sacrifice, relied upon greatly by its allies throughout its history. When ever there is a international threat, other cowardly western countries take a step back, leaving the USA to take the lead.

America did not "help" Europe for free.


The fact that you would expect the USA to turn itself into a war machine for FREE, is indicative of a mentality that is indeed dependent upon the USA.

who did America sell weapons to during WW2?? Both sides

If you're referring to Russia, they were an Ally during WWII, dipstick.

Unbelievable. No country on this planet even comes close to the USA in technological innovation, from space exploration, satellite, medical, military, internet, science, etc... and in the electronics field the USA has companies worth more than entire countries GDP.

p.s. I'm not an American, so i'm not bias, nor bias from the idiot liberal "hate america" fad.

Precisely, ....you have to go all the way back to the USA's infancy to find an example where the USA needed another counties help.

The shocks will be many as the USDollar struggles and falls off the global financial stage in full view. The desperate maneuvers like in Syria and Ukraine should be seen as last ditch efforts to save a dying system. For two decades the USDollar has been defended by military means. Worse, for 50 years the USGovt has been a hidden nazi enclave of wicked fascists who have hidden behind their overt disdain for communism, with Kissinger the flag bearer, with Brzezinski the ideologue, with Papa Bush the executor, with narcotics and genetics and gold thefts their principal agenda. The official US support of fascist regimes includes a list of nations as long as your arm.

Since 2008 when the Lehman kill was executed in order to rescue Goldman Sachs, when Fannie Mae was hidden under the USGovt roof to prevent its $trillion fraud from being exposed, and when AIG was tucked in the USFed basement closet for ample monetized rescues to patch the derivative black holes, the Anglo-American banking system has indeed been going through trials and tribulations, leading to its death throes. The climax of the banking system death process is upon us finally, the fibrillations of sudden illiquidity against the backdrop of relentless unforgiving insolvency so evident to those with eyes that function.

Never before has the USGovt been so plain in its fascist ways, with abuses on domestic soil and installed nazi regimes on foreign soil. They kill economies systematically. They wage war relentlessly, using it as a business initiative. They control bank movements obsessively. They monitor human movement compulsively. In Kiev were seen the swastikas on armbands.
