  • A jubilant CMS Control Room, shortly after the LHC provided the first pPb collisions with stable beams.

  • One of the first proton-lead collisions of 2013 in the CMS detector, with all subdetectors running.

The LHC has just delivered the first pPb (proton-lead) collisions with stable beams of 2013 and CMS is happily running with all sub-detectors on. We are also having common triggers with TOTEM and everything is behaving very well.

Thanks a lot to all the operations crews and experts for their availability and their effort to have CMS ready for the pPb collisions, after the Christmas break, in such a short time.
