а в чём прикол комикса?

Please find below the schedule for LHC startup in early September. The plan is to circulate beams in the 2nd week of September, followed by a short period of collissions at injection energy (900 GeV cms), and then ramp up and collide at 10 TeV..

CERN announces start-up date for LHC

Geneva, 7 August 2008. CERN* has today announced that the first attempt to circulate a beam in the Large Hadron Collider (LHC) will be made on 10 September. This news comes as the cool down phase of commissioning CERN's new particle accelerator reaches a successful conclusion. Television coverage of the start-up will be made available through Eurovision.

The LHC is the world's most powerful particle accelerator, producing beams seven times more energetic than any previous machine, and around 30 times more intense when it reaches design performance, probably by 2010. Housed in a 27-kilometre tunnel, it relies on technologies that would not have been possible 30 years ago. The LHC is, in a sense, its own prototype.

Starting up such a machine is not as simple as flipping a switch.
Commissioning is a long process that starts with the cooling down of each of the machine's eight sectors. This is followed by the electrical testing of the 1600 superconducting magnets and their individual powering to nominal operating current. These steps are followed by the powering together of all the circuits of each sector, and then of the eight independent sectors in unison in order to operate as a single machine.

By the end of July, this work was approaching completion, with all eight sectors at their operating temperature of 1.9 degrees above absolute zero (-271°C). The next phase in the process is synchronization of the LHC with the Super Proton Synchrotron (SPS) accelerator, which forms the last link in the LHC's injector chain. Timing between the two machines has to be accurate to within a fraction of a nanosecond. A first synchronization test is scheduled for the weekend of 9 August, for the clockwise-circulating LHC beam, with the second to follow over the coming weeks. Tests will continue into September to ensure that the entire machine is ready to accelerate and collide beams at an energy of 5 TeV per beam, the target energy for 2008. Force majeure notwithstanding, the LHC will see its first circulating beam on 10 September at the injection energy of 450 GeV (0.45 TeV).

Once stable circulating beams have been established, they will be brought into collision, and the final step will be to commission the LHC's acceleration system to boost the energy to 5 TeV, taking particle physics research to a new frontier.

'We're finishing a marathon with a sprint,' said LHC project leader Lyn Evans. 'It's been a long haul, and we're all eager to get the LHC research programme underway.'

CERN will be issuing regular status updates between now and first collisions. Journalists wishing to attend CERN for the first beam on 10 September must be accredited with the CERN press office. Since capacity is limited, priority will be given to news media. The event will be webcast through http://webcast.cern.ch, and distributed through the Eurovision network. Live stand up and playout facilities will also be available.

A media centre will be established at the main CERN site, with access to the control centres for the accelerator and experiments limited and allocated on a first come first served basis. This includes camera positions at the CERN Control Centre, from where the LHC is run. Only television media will be able to access the CERN Control Centre. No underground access will be possible.
