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 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?

CPP Test. Mon evening Aug 31 - Tue morning Sep 1

  1. Fill Target :
  2. Install 1 Pb sheet: 1 hr
  3. Data CPP Test configuration- Full Target/no DIRC/1Pb : 1 hr
  4. Install 0 Pb sheet: 1 hr
  5. Data CPP Test Configuration - Full Target/no DIRC/ 0Pb : 1 hr
  6. Install 2 Pb sheets: 1 hr
  7. Data CPP Test Configuration - Full Target/no DIRC/2Pb : 1 hr
  8. Empty Target :
  9. Install 1 Pb sheet: 1 hr
  10. Data CPP Test configuration- Empty Target/no DIRC/1Pb : 1 hr
  11. Install 0 Pb sheet: 1 hr
  12. Data CPP Test Configuration - Empty Target/no DIRC/0Pb : 1 hr
  13. Install 2 Pb sheets: 1 hr
  14. Data CPP Test Configuration - Empty Target/no DIRC/2Pb : 1 hr

Restore GlueX configuration and prepare for GEM-TRD Test. Tue day Sep 1

  1. Fill Target
  2. Restore nominal GlueX configuration: 4 hours.

Required personnel

  1. Two persons needed to install/remove Pb Sheets
  2. Mark Dalton has volunteered to come in on Monday evening if a third person is required to monitor the target.
