Previous Day

  • Lab in-personnel: Matt, Derek
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.
1315 Got some cable from Bill Gilbert that will be good for the warm connector for the thermometer - 4 conductors and a shield.
1330 Finish mounting Goldman thermometer brass base nut to housing lid.
1430 Examine Tower thermometer wire. Remove all Kapton tape. Noticed that one wire was loose on the plug. Could this have been loose for a long time and could it have caused the thermometer instabilities? Seems unlikely but who knows. Plan to cut the thermometer wire shorter, that extra length is never useful under ordinary circumstances. Can make an extender for unusual setups.

The wire seems like special thermometer wire, it's four thin magnet wires stuck together and four different colors. I wonder where you can get that? Looks like something similar with the Goldman thermometer.
