Reconfiguration and Commissioning

  • Starting on April 18 at 8am:
 - Energy change: 4 pass --> 3 pass (8 hours)
 - Beam energy measurement (2 hours)
 - Change DAQ to two independent DAQs (10 hours)
 - Initial checkout (8 hours)
 - BCM calibration (1 hour)
 - Boiling study on 4He and deuterium (2x4 hours)
 - Rate-dependence tests (4 hours)

1st phase: Helium-4 and Deuterium running

The time listed is the total time needed. It should be divided by two if the kinematics point is taken simultaneously by the the two HRSs.

Total time needed: 156.6 hours/2 = 78.3 hours per HRS (production) + 3.5 hours (optics) + (target motion) + (kinematics change)
