At Peter Woit's blog we read that we shall see some low-power fireworks in late summer.
"Robert Aymar, the Director General of CERN, has announced that the LHC will operate when it starts up this year at an energy of 5 TeV per beam (10 TeV total center of mass energy), rather than the design energy of 7 TeV per beam. To operate the LHC magnets at the highest current and get to 7 TeV requires a time-consuming sequence of powering tests and quenches, so the decision was made to put this off until the winter shutdown. With this decision, the process of beam commissioning can start soon after all sectors have been cooled down, and this is now scheduled for mid-June. Beam commissioning should take two months, with first physics collisions thus scheduled for late summer."
