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.
