>From imaging the carbon hole we settled on requesting a 0.6x0.6 mm raster from MCC, this is 2x2 mm on target. - https://logbooks.jlab.org/entry/4282509

Significant amount of time spend during the day yesterday working on GEM HV and DAQ issues. - https://logbooks.jlab.org/entry/4282500

Detector checkout was completed during swing shift with LH2. See 50k replays for details on individual detectors. 

The GRINCH is having some issues that are currently being debugged - https://logbooks.jlab.org/entry/4282816

At the beginning of owl we starting taking GEM-Hall alignment data on single carbon foil and magnets off. We acquired about 20M events. 

For the rest of owl calibration data was taken without the steel analyzer on LH2 and LD2 with SBS fields at 100%

The hall is currently in controlled access for the Techs to insert the steel analyzer. We should be able to come back up around noon and continue with the run plan and hopefully soon begin production running.


We will meet a 3:30 pm on the second floor of the counting house and also via zoom:
