Summary
Steady data taking (Production) on Slanted Carbon with ~10µA of
un-rastered beam.
Significant Events
- 08:00 Began the shift in the middle of Run 1923, beam current at ~10µA, un-rastered.
- 08:13 MCC tells us there's an RF zone
dropout. Beam away for at least 10 minutes.
- 08:58 Beam returns.
- 11:16 Alarm on Beamline HV crate.
(139581)
- 11:59 HV was raised for bars 54,55 and
for dE-2L
(139584).
This may have been done after Run #1926 (or during run #1927).
- 14:10 Noticed that the N2
level in the Right Q3 was low (<10%). Started a stripchart
(139594).
A beep also occurred around this time, in the vicinity of the
"Detectors Flammable Gas Sensors" Box. Nitrogen level increased to
above 60% after a few minutes.
(139596).
