Test sequence

Possible test schedule by Tim Media:CPP_Tests_Aug2020.pdf

Total estimated time for test including installation, data taking and reinstallation of GlueX is 34 hours.

CPP Preliminary baseline measurements

These will be conducted by Ilya during Sat Aug 29 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: Day Mon Aug 31

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