Assume that nominal the GlueX configuration consists of

  • No Pb shielding
  • DIRC installed
  • Solenoid field at 1350 A

CPP Test Configuration

  • With and without Pb shielding
  • DIRC removed
  • Solenoid field at 1350 A (no change)

Possible sequence and times

  1. CPP test DAQ setup: 2 hrs
  2. Data GlueX configuration - Full Target/DIRC (repeat from Dec 2019): 2 hrs
  3. Empty target : 1 hr
  4. Data GlueX configuration - Empty Target/DIRC : 1 hr
  5. Configure experiment for CPP Test: 12 hr
  6. Fill Target :
  7. Install 1 Pb sheet: 1 hr
  8. Data CPP Test configuration- Full Target/no DIRC/1Pb : 1 hr
  9. Install 0 Pb sheet: 1 hr
  10. Data CPP Test Configuration - Full Target/no DIRC/ 0Pb : 1 hr
  11. Install 2 Pb sheets: 1 hr
  12. Data CPP Test Configuration - Full Target/no DIRC/2Pb : 1 hr
  13. Empty Target :
  14. Install 1 Pb sheet: 1 hr
  15. Data CPP Test configuration- Empty Target/no DIRC/1Pb : 1 hr
  16. Install 0 Pb sheet: 1 hr

Target dates:

  • Our preference is to conduct the CPP test before the scheduled end of the run period.
  • However, we recognize there are many advantages of scheduling the test to coincide with the second pass change on the accelerator schedule (nominally Sep 4), but with the danger that the entire run gets cut short. We request that an earlier date be considered if the opportunity arises.

The DIRC will have to be surveyed following the test.
