Final LHC Synchronization Test a Success

Geneva, 25 August 2008. CERN has today announced the success of the second and final test of the Large Hadron Collider’s beam synchronization systems which will allow the LHC operations team to inject the first beam into the LHC. Friday evening 22 August, a single bunch of a few particles travelled down the transfer line from the Super Proton Synchrotron (SPS) accelerator to the LHC. After a period of optimization, one bunch was kicked up from the transfer line into the LHC beam pipe and steered counter-clockwise about 3 kilometres around the LHC. “Thanks to a fantastic team, both the clock-wise and counter-clockwise tests went without a hitch. We look forward to a resounding success when we make our first attempt to send a beam all the way around the LHC,” said Lyn Evans, LHC Project Leader. Both the counter-clockwise and clockwise tests are part of the preparations to ready the LHC, the world’s most powerful particle accelerator, for the eventual acceleration and collision of two beams at an energy of 5 TeV per beam. This unprecedented event is foreseen to take place by end 2008.
