Status

RHS optics data taking revisited due to wrong polarity setting for RHRS Q1. Took RHRS optics data with the correct polarity for a various magnet settings as requested and analyzers are looking at the data. After the optics data taking, Bob started working on coincidence timing. While trying the coincidence timing, had several issues; UPS problem (https://logbooks.jlab.org/entry/3650859) - twice last night, LHRS Q2, Q3 current readback. Didn't see the coincidence time peak https://logbooks.jlab.org/entry/3650893
