Minutes of the forward endcap EMC SeeVogh meeting, 6th of July 2015, 14:00-15:00

Presence:

  • Basel: excused
  • Bochum: Claudius, Fritz-Herbert, Malte, Miriam, Patrick, Tobias H., Tom, Cathrina, Malte, Matthias, Stephan
  • Bonn: Christoph
  • Groningen: -
  • Uppsala: -
  • GSI: -

Bonn VPTT subunit cosmics setup:

  • Plot of shaper-included measurement shown by Tobias
  • The absolute values need correction factors due to impedance mismatches and/or choosen shaper gain ranges
  • Looks like "preamp-only", "shaper-included" and "earlier oscilloscope" measurements from Bonn will give consistent results with cosmics
  • However, the beam data results from last year's Bonn beam time significantly differ
  • Difference may come from shaper: at beam time we had to use the low gain, with cosmics the high gain branch
  • Agreed to end this cosmics data taking at Bonn
