Some tests before warmup:
Try swapping to Side1-readout (Side2-bias).
Could apply ~ -100V without excess leakage, somewhat higher than the other side. But excess leakage seen when I tried -120V. Pattern is somewhat different
Could only get traces in two Side1 channels, others could not be unrailed. SQUID problems? Couldn't test SQUID response because the SQUID tuning tool isn't working in the new MIDAS installation (and I couldn't figure out how to do it “manually” through the ODB)
Tried leaking helium gas into bag around stripline elbow, only for a few hours because it used up to much of the cylinder
Plan to skip today's LHe transfer and start warmup
Will do electrical checks at breakout box to look for new problems
can also try leak checker on IVC
can begin disassembling NaI array and shield whenever, but should talk with Anthony first to see if there are more NaI array measurements we should take.
