Previous Day

Status: warmup finished. All mixture in dump, fridge isolated. LN2 traps warm and pumped out. 1K Pot needle valve closed. IVC open.
1015 Tower = 24.2 C on lab thermometer. MC(Cernox) = 295.8 K on LakeShore display, 297.2 K on LabVIEW vi. So the vi is closer.
1110 Disassemble 4K stage
Thinking about leaving 4K stage out in the next run, with no charge channels, FETs off. We would probably want to leave off the entire shield. It currently serves two purposes: heatsink the tower 4K stage, and serve as a 4K shield between the cooler stages (100mK can) and warmer stuff. But with the FETs off, there's nothing warmer than 4K, and neither of these are necessary.
1330 Disassemble 600 mK and 100 mK stages
