LHC beam particles observed by a detector


One of the other three LHC experiments, LHCb, had the honor of observing the first beam particles!  The diagram in my August 24 post shows the parts of the LHC that have seen beam so far, which includes LHCb (on the red line).  All four detectors are built around the beamline, not in it, so they’re not observing the beam protons directly.  (No detector ever could— it would get fried!)  They’re observing the “beam-halo” muons that accompany a beam (described in my August 8 post).  This is normally considered an unwanted background, but we’re all excited anyway.

This is from a news article about the milestone:

Marco Gersabeck, a PhD student at the University of Glasgow, said: “It’s working! And it is providing me with the type of particle tracks that I will use to align its sensors to an accuracy of a few millionths of a metre.”

A fellow aligner!  I think we’re the only people who are actually happy about Beam-Induced Backgrounds.  Except right now, now while we’re all excited about anything that trickles out of the LHC.

    these are very interesting information followed prof dr mircea orasanu and prof drd horia orasanu and so must extended

    in these can be considered important situations as prof dr mircea orasanu and prof drd horia orasanu concerning and followed a somewhat academic question since nobody has ever experimentally observed a scalar term in the Schrödinger equation of gravitating matter, for a point particle in a curved space, even if torsion is neglected, and it is not even clear, whether gravity will generate torsion outside spinning matter.
