Previous Day

  • Lab in-personnel: Himangshu, Matt
Status Run 76 finished
Setup DCRC33(2)→HV control, NaI trigger signal → DCRCX(4)
IVC closed and Turbo pumping for a few days. No tower - this is just a leak test.
1330 Continue replacing Face 6 Pins 1-4, 6-9 wires between Still and 4K with manganin. Managed to get all 8 soldered on without shorts (took a few hours). Also wound up knocking off the socket at the bottom for Pin1 - was able eventually to solder it back on, not sure how stable it is. After replacing the cover plates we found more shorts, specifically at the Still PCB (center cover plate), so we'll have to fix that tomorrow. If nothing else can block it with Kapton tape.
