10:00AM Run Meeting, Counting house meeting room (200C)

RC: Carlos Ayerbe

HV issues (https://logbooks.jlab.org/entry/3806487):
- in order to run cosmic, we tweak the HV GUI to short the delay time to ramp up the GEM voltage and reduce the cathode to -5500V
- we were able to run op to -5600 (I guess Mohammad raised to -5650 and later in the night to -6100V but not sure when)
- From the strip chart it is clear the RTPC trips around 04:30

Nate D. notice that the drift pressure was low (02:45), and no bubbles. I checked the gas shed and the manometer indicates 10psig in the pre-mix lines. We need to check that.

BPM alignment ongoing.
Jiwan and Nathan B. should take a decision of the HV modules (keep in Yuri's crate, return to the original, make changes in software...?)
Install bubblers camera.
turn on blower (sucker).
RadCon to move RTPC1 to EEL bldg.
From Eugene:

What magnetic field configuration are we going to start with? Torus Inbending? outbending? Solenoid polarity and strength?
