The Large Hadron Collider has given physicists a large quantity of data since the first run in 2009. The LHC is in need of a little vacation. “Long Shutdown 1″ (LS1) will start on February 14 2013, Valentines day. LHC will be out of commission for almost two years, LHC will be back for an operation at higher energy.
“A whole series of renovation work will be carried out around the LHC during LS1” - Simon Baird, deputy head of the Engineering department
“The key driver is of course the consolidation of the 10,170 high-current splices between the superconducting magnets. The teams will start by opening up the 1695 interconnections between each of the cryostatsof the main magnets. They will repair and consolidate around 500 interconnections simultaneously. The maintenance work will gradually cover the entire 27-kilometre circumference of the LHC.”
The LHC will be upgraded and renovated during the time off. In the framework of the Radiation to Electronics project (R2E), sensitive electronic equipment protection will be optimized by relocating the equipment or by adding shielding.
Major renovation work for the Proton Synchrotron (PS) and the Super Proton Synchrotron (SPS). During LS1 the upgrade of the PS access control system, which includes the installation of 25 new biometrically controlled access points, will continue. The whole tunnel ventilation system will also be replaced, with 25 air-handling units. At the SPS, about 100 kilometres of radiation-damaged cables used in the instrumentation and control systems will be removed or replaced.
