Up and delivering ~22uA

2 hours of downtime during owl

Resolved beam position drifting issue after harp scan by halting orbit locks (https://logbooks.jlab.org/entry/3622232) - now added to the Shift Plan Standing Orders

Swing

LHRS F1 TDC resolution lock failure (slot 16): https://logbooks.jlab.org/entry/3622128

Alexandre changed LHRS F1 bin size from 56 ps to 58 ps. Updated analyzer to show the warnings up to 10k times instead of 10. The same warning did not come back so far. Analyzers checked timing distributions (https://logbooks.jlab.org/entry/3622495)

Hit overflow warnings during replay: https://logbooks.jlab.org/entry/3622273 - Hit overflow warnings from time to time is ok

Owl shift

Data taking without any major issue (from the hall)

Day shift

Data taking without any major issue (from the hall)

NOTE:

Remind MCC about orbit locks when they take harp scan (now in standing order)

Pay attention to energy shift and energy lock/FB system (they should be ON) and raster.

Check the truck ramp door indicator (orange cone in the camera screen) from time to time

Plan:

Continue tritium data taking. Currently the plan is changing to hydrogen on Friday. No momentum/spectrometer angle changes.
