No, nothing doing yet. If you were following the LHC Countdown webpage like a lot of people were I'm afraid its irrelevant as its not owned or operated by CERN or anyone who works for them.

According to someone I spoke to who works on one of the experiments they're looking to have the first beams injected at the end of this month or the beginning of August, which will begin the long process of gradually starting it up properly. They're hoping for the first low energy collisions around October/November before they go into the winter cooldown.

It won't be until next spring that they start really ramping things up properly and it'll be a while after that before anyone starts to see any interesting results. There's no big red "ON" button for them to push, really.
