Waiting for (a lot of) Collisions

Since my last blog post, “Waiting for Collisions“, we’ve had them and plenty of excitement.  Each of the four big experiments recorded data in which they were able to see evidence of collisions in their detectors.  Last Thursday, there was a meeting where the LHC and the experiments showed some first results, and all of the presentations were very encouraging.  But what we have seen so far has only been the warmup.

We are now eagerly awaiting a significant number of collisions, and to collect data where we can see not just a few interesting events, but start analyzing data with large numbers of particles and testing the performance of the detector.

I am in the ATLAS control room today on shift.  The LHC has been doing tests with beams in the LHC in preparation for the first collisions with higher intensity beams.  They are testing all the safety systems, and doing everything they can to guarantee the proton beams are well controlled to protect the detectors from damage.

Hopefully we will have collisions in the next few days, and the next week should be even more interesting than the last!

    And alas a power failure. Can anyone at cern comment if the power went out at residences, offices etc?

    To Harbles:
    I can only say that CERN’s hostel 38 was out of power last night. There were two power dips at that building – the first lasted for a few seconds, then followed by a long one, a minute or so later. WiFi went down too. Emergency lighting in the hostel’s hallways and neighboring buildings, as far as I could see, was up.
