When do physicists expect to get usable data from the new LHC collider in Cern, Switzerland?

Is LHC up and running yet? How much data, and how long is it expected to take to have enough to formulate conclusions or formulate new theories?When do physicists expect to get usable data from the new LHC collider in Cern, Switzerland?
It is currently not up and running, due to some damage it sustained late last year. Usable data will probably take a couple years to get out, it's hard to tell how long exactly. There's a lot of calibration and test runs that have to go in this kind of thing before you can be reasonably certain that your data is good.
