- Lab in-person: Matt
- Virtual partner: Ruiren, Derek
| Status | Run 73 deinstallation. 1K Pot pumped out and isolated. Fridge and 4He and LN2 Trap 1 isolated, not pumped out. Cryostat vacuum jacket pumped out. IVC at 1 bar. MB in pit, clean tent erected. |

| 1500 | Matt enters lab |
| 1500 | MC(Cernox) = 297.1 K |
| 1530 | Check HP desk multimeter for 4-wire resistance measurements. We want to use this to test solder connection resistances at 4K with electroplated NbTi. Looks like with shorted banana cable it can read resistances as low as a few mOhm. |
| 1610 | Matt leaves lab. |
