The LHC shut down yesterday for an end-of-year break after a very successful initial period of beam commissioning at beam energies of 450 GeV and 1.18 TeV. Tomorrow at CERN there will be public reports<\/a> about the state of the LHC and the initial results from the experiments. I gather that by now all sorts of particles have been rediscovered, including kaons and lambdas, here are some details from Jim Pivarski<\/a>.<\/p>\n

There’s now a tentative schedule 2010 out. Hardware commissioning of the new quench protection system, allowing beam energies up to 3.5 TeV, will begin on January 4, and be completed by February 15. A new checkout to prepare for beam commissioning will take place Feb. 17-19, and next injection of a beam into the LHC should be around February 20. Commissioning of 3.5 TeV beams and some pilot physics runs at that energy should take a month or so, with the first regular physics runs at 3.5 TeV\/beam beginning around March 25. A tentative month-long shutdown to reconfigure the machine to run at higher energy (up to 5 TeV\/beam) is scheduled for May 3-June 2.<\/p>\n

From January 25-29 machine experts will meet in Chamonix to discuss whether to try and run at 5 TeV\/beam in 2010, and how to implement this if it seems feasible. Plans will also be made for the late 2010-2011 shutdown. This will require deciding what to do about all the problematic splices in the machine in order to allow operation at the design energy of 7 TeV\/beam, as well as understanding how much retraining of the dipoles will be needed in order to get to that energy. Current plans call for a “long shutdown” in 2013-4 to begin some upgrades of the LHC, and this is another topic that will be discussed.<\/p>\n

While news coverage of the LHC in science magazines like Science News has been a mixed bag, often focussing on extra-dimensional speculation irrelevant to the actual science that will get done there, there’s a quite good new article here<\/a>, in a surprising location: Vanity Fair. The LHC has become a real celebrity…<\/p>\n","protected":false},"excerpt":{"rendered":"
