Large Hadron Collider set for high speed bash by early April: CERN

The particle collider is inside a 27-kilometre tunnel straddling the Franco-Swiss border near Geneva
A view of a superconducting solenoid magnet at the European Organization for Nuclear Research (CERN) near Geneva. The European Organisation for Nuclear Research said that the world's most powerful atom smasher will be brought up to unprecedented power by early April.

The world's most powerful atom smasher will be brought up to unprecedented power by early April, the European Organisation for Nuclear Research said on Wednesday.

"We hope to have collisions at 7.0 TeV (teraelectronvolts) at the end of March or the beginning of April," CERN spokesman James Gillies told AFP.

The 3.9 billion euro (5.6 billion dollar) (LHC) was restarted after a winter break two weeks ago to ready it for collisions at unfathomed energy levels.

The -- inside a 27-kilometre (16.8-mile) tunnel straddling the Franco-Swiss border near Geneva -- is aimed at understanding the origins of the universe by recreating the conditions that followed the .

"During this first physics run, the LHC experiments will open up the biggest range of potential new discovery that has seen in over a decade," said in a statement.

Gillies reiterated that the experiments would run for 18 to 24 months before another technical shutdown.

That halt would last for eight to 10 months while the LHC is prepared for the next stage, full power operation with beams running at 14 TeV, he added.

CERN's engineers decided in January to change the annual cycle they followed with its previous, smaller, accelerator, which used to be shut down for four months in winter for maintenance.

Instead they were aiming for longer period of continued operation with the LHC followed by a longer shutdown when needed, because of the total of two months its takes to heat up then cool down the huge cryogenically cooled colliders before and after maintenance.

The collider was revived from a 14-month breakdown last November, following a technical glitch that put it out of action days after it was launched in September 2008.

Bee seen, or die.

CERN is using media with a new strategy. Post daily, no matter if you have anything new to say. This keeps CERN in everybody's thoughts constantly.

Of course, the aim is to make CERN and the LHC household words, all the way to the remotest Lapland log cabin or Rio shantytown. This makes it vastly easier to secure funding in the coming years, and it helps pre-empt competition.

Survival of the shrewdest. Watch it, Tevatron guys, or you'll be annihilated by oblivion.

..Post daily, no matter if you have anything new to say...
Funny point is, at the case of LHC damage in September 2008 first photos of accident were released just after three months, i.e. in December. This is simply how socialistic PR is working: announce every progress loudly, but cover real problems. Nothing very new in this context.

I think the original thought was to bring it up pretty "fast" to the 14 TeV-level but it crashed at far lower level. Then I red just the other day that the 14-level can't be reached without at least a year of complete refurbish of some structures ... even after the post-crash repair, they don't trust the current construction of all the machine to manage 14-level ("Higgs-level"). So any "Higg-mania" is not expected to happen within the next 2-3 years. BUT we have to keep the happy mood up ... ;)

I do not believe that is true -- the level of 7 TeV is a lot higher than needed to find the Higgs boson if it exists. The upper range is well below 7 and FermiLab has an adequate power level to search for and find it given enough time... but it is up for decommission in like a year and a half. It is very possible that they could find the particle... just very unlikely

-- In any event @ 7 TeV they will acquire 1 Femtobarn ^-1 collsions in just over a year. In retrospect it took Fermilab a decade to acquire that many collisions. Which is supposed to be a ton of data to go through.

If by pretty fast you mean they were going to take two years to get to 14 TeV then yes -- but the current director has stated that that was a bit too ambitious, due to the size of the accerelator and shear complexity of getting to 'know' it.

14 TeV is ' I beleive ' to gaina foothold into new territory.. to explore the world of possibly new physics and at that level something new should emmerge

Mar 11, 2010
El Nose, you could be right 7 TeV is enough to find Mr Higgs, if he exists. Maybe the probability to encounter that evasive man, is bigger at 14 TeV ? Personally I have no idea ;)

The LHC is very open to public. An example of the data available to the public can be found at:

I've spent hours watching every little activity and the lower power collisions. It's great fun. I can't wait to see the fireworks the higher power collisions will create.

The LHC is very open to public
I'm just saying, the first photos of 2008 accident were released three months after accident, when fiscal year for grant dotations was closed. It's as simply, as it is and it has no meaning to cover this censorship too, as it only demonstrates the way, in which LHC proponents are adjusting reality to suit their needs.

Seven Reasons for Demanding an LHC Safety Conference

LHC to shut down for a year to address design faults:

As we can see, all reasons presented by prof. Otto Rössler are extremelly simple and no knowledge of complex physical theories is required to understand it. Therefore the fact, these risk factors were ommitted/neglected from all CERN security analysis is indicating, mainstream physics is facing one of its biggest scandals, because of apparent manipulation of accessible facts.

These people know it might be dangerous, yet they continue anyway!

From Wikipedia: Mad Scientist:
...Mad scientists also, whilst definitely being intelligent, if not necessarily brilliant, usually fail to think things through to their conclusion...

Some excerpts from the LSAG (CERN safety committee) summary report:
Collisions at the LHC differ from cosmic-ray collisions with astronomical bodies like the Earth in that new particles produced in LHC collisions tend to move more slowly than those produced by cosmic rays. Stable black holes could be either electrically charged or neutral.

If stable microscopic black holes had no electric charge, their interactions with the Earth would be very weak. Those produced by cosmic rays would pass harmlessly through the Earth into space, whereas those produced by the LHC could remain on Earth.
... So just what do they think stable, neutral black holes, which remain on Earth, might do next?

Mar 14, 2010
Busza, Jaffe, Sandweiss, and Wilczek regarded a one-in-5,000 risk of destroying Earth as "comfortable."


It's a risk of Hirschsprung's disease, Down's syndrome or the risk of melanoma syndrome development during human lifetime.

Nothing - or they would lose their jobs otherwise...
