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)
