Summary Mostly production data, this shift. Lost
EPICS readback of the radiator RTD.
Significant Events
- 00:00 Began shift with the start of Run 1608 on the 3He, 45µA,
Radiator In.
- 00:08 Xiaodong opens the FPP door.
- 01:45 Radiator out. Asked for 50µA.
- 02:08 A couple channels in the beamline
HV crate tripped. Power cycled to bring them back up.
- 02:50 6% radiator in, reduce beam current
to 45µA.
- 03:50 Noticed that we lost readback on
the radiator temperature. Paged RC.
- 04:38 Moving spectrometers to 67.32°
- 04:46 Move to carbon optics. Radiator
out. Ramp down raster.
- 05:06 Move to 3He. Radiator
In. Raster back on.
- 06:00 Moving spectrometers to 65.32°
Moved to carbon target.
- 07:15 Radiator out. Asked for 50µA.
- 08:00 Pass Run 1608 to day shift.
