CPP Preliminary baseline measurements

These will be conducted by Ilya during Fri Aug 28 4am-10am shift.

  1. CPP test DAQ setup: 2 hrs
  2. Set coherent peak to 6 GeV
  3. Data GlueX configuration - Full Target/DIRC (repeat from Dec 2019): 2 hrs
  4. Empty target : 1 hr
  5. Data GlueX configuration - Empty Target/DIRC : 1 hr
  6. Restore coherent peak to 8.6 GeV

Installation/setup of CPP Test

  1. Pass change for Hall A/C Day Mon Aug 31
  2. Configure experiment for CPP Test: 12 hr. Mark Stevens and staff.
  3. Training for Pb sheet install/removal?
