  • 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
  17. Data CPP Test Configuration - Empty Target/no DIRC/0Pb : 1 hr
  18. Install 2 Pb sheets: 1 hr
  19. Data CPP Test Configuration - Empty Target/no DIRC/2Pb : 1 hr
  20. Fill Target
  21. Restore nominal GlueX configuration: 4 hours.

Total time = 34 hours

Suggested personnel:

  • CPP will take necessary shifts during the test
  • May have up to 2 persons in the Counting Room and to install/remove Pb Sheets

The DIRC will have to be surveyed following the test.
