- Lab in-personnel: Matt, Himangshu, 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. | |
| 1240 | Perform electrical checkout on detector S104: |
