JLab: CEBAF Center, Room F326/327

Agenda

  1. Announcements
  2. Review of minutes from the previous meeting
  3. PMT order
  4. Cosmic data
    • looking at signal amplitude vs time difference for 1350V
      Amp vs dt 1350V paddle11 plane2.jpg
      Amp vs dt 1350V paddle11 plane2 zoom.jpg
    • The flash250 ADC op-amp signal inverting input causes a baseline shift that feeds back to the input to the leading edge discriminator resulting in a miss match between threshold setting and actual threshold.
    • other examples of amplitude vs dt paddle 18 plane 1:
      Amp vs dt 1350V paddle18 plane1.jpg
      or paddle 20 plane 1
      Amp vs dt 1350V paddle20 plane1.jpg
      or paddle 20 plane 2
      Amp vs dt 1350V paddle20 plane2.jpg
