Previous Day

  • Lab in-personnel: Matt, Himangshu, Giulia
Status Run 75 prep.
All mixture is in dump. Fridge isolated. 1K Pot isolated. LN2 Trap 2 still has contaminants in it. MB in pit, clean tent erected. Cryostat vacuum jacket (CVJ) pumped out. IVC open. Tower removed.
1145 Bring S104 to wirebonding lab for repairs. Rebond DIB1pC, DIB1pD, DIB4pD. These are all Side2 channels. Now all Side2 channels are good. (These were relatively easy, bonds aren't too long. Completed all three in about 30 minutes.)
1345 Disassemble tower in clean room
Looking at Goldman thermometer. We could drill a hole in the detector lid and screw the brass base onto that lid - then the Goldman thermometer would just sit on top of the tower.
The Goldman thermometer plug is not the size we use, nor is it the usual gender. We could solder a female connector onto it of the same type we have for the Tower thermometer.
Should we consider redoing the tower thermometer wiring??
For twisted-pair phonon channel connectors: we could solder pins to some boards, would have to jumper the SCAB boards for charge lines. Or, could just have individual twisted pairs with pins soldered to the ends (ala CUTE). I think I found the spool of wire used before. Need to find our stash of MillMax pins, not sure where they are.
