GlueX Time-of-Flight Meeting
Tuesday, July 5, 2016
11:00 am EDT
JLab: CEBAF Center, Room F326/327

Agenda

  1. Announcements
  2. Review of minutes from the previous meeting
  3. PMT Gains: The folowing plots show the signal peak amplitude for hits that are matched to tracks
    the data are from different runs where we did a beam current scan starting with 40nA and going up to 150nA. At 40nA beam current the peak amplitudes look still reasonable, but already at 80nA a degradation is noticeable which becomes critical at even higher currents(luminosities). The radiator was 50um diamond.
    • Run 11634 with 40nA beam current:

    • Run 11637 with 110nA beam current:
