    keyword=Neutron arm HV questions

    Well, we're still waiting for beam to see if the left PMT in bar 5 has the correct gain after the HV adjustment...

    Some remaining questions that should be addressed:

    1. IF the HVs are logged in the data stream at the start (end?) of each run would someone please extract them for runs 2277 and 2278 and look for a change in values for the NA-P1 bar 5 PMTs. Hell, do a diff on all 'meas HVs' and log any discrepancies -- nothing should have changed.

    2. Nothing has been done to address the low ADC spectrum on the right PMT for bar 5 (the set, meas, demand values in the GUI were all self-consistent). ** Should the HV be bumped up? **
