Summary
Steady data taking with 20µA un-rastered beam on the Slanted
Carbon target, since 09:30. Did a harp scan after the Hall-C beam
studies and CHL recovery. Had a couple issues with the SRC HV.
Significant Events
- 08:05 Hall at beam permit.
- 09:00 Started to get tune beam.
- 09:10 Started to get CW beam (20µA)
- 09:20 Performed a harp scan
(139742)
- 09:28 Prescales set for production at 20µA, un-rastered beam on Slanted Carbon.
- 09:42 Reset the lower neutron detector HV crate
(139744)
- 11:45 Lost slow controls of SRC HV (All
fields were white). All of the veto scalers were black. After this,
Ron had to turn on one of the crates manually
(139749).
- 14:50 Program Deputy stops by to tell us
they'll be doing a 15 minute beam study with beam in the injector. Should
occur in about 30 minutes.
- 15:16 MCC begins their study.
- 15:30 MCC is ready to resume CW to the hall.
Data Run Summary
- 08:00 Run 1978 -
Cosmics Run (Slanted Carbon). Continued from owl shift.
- 09:02 Run 1979 -
Run with tune beam (Slanted Carbon).
- 09:16 Run 1980 -
Run with harp scan (Slanted Carbon).
- 09:28 Run 1981
- Production Run (Slanted Carbon). Lower neutron HV was off
during first half the run.
- 10:41 Run 1982
- Production Run (Slanted Carbon). Lost SRC HV communication.
Had to turn back on one of the crates.
- 11:55 Run 1983 -
Production Run (Slanted Carbon).
- 13:12 Run 1984 -
Production Run (Slanted Carbon).
- 14:21 Run 1985 -
Production Run (Slanted Carbon).
- 15:35 Run 1986 -
Production Run (Slanted Carbon). Passed to swing shift.
