| Setup | Run 73. DIB 1/3/4 → Stripline 43/48/41 → pi-filters 1/2/3 → Cable 3/1/2 → nothing/nothing/accessory_interposer → HV_Conn 1/3/2 → HV 1/2 → DCRCX(4)/DCRC55(1)-master; DCRC33(2) → HV control. DCRCs on overnight. Lead/poly shield erected (4 lead walls, 2 poly walls). |
| 1022 | MB = 61.8% (5.1% lower than predicted by Bath Calculator) |
| 1215 | Zach body temp = 99.2 |
| 1235 | Zach arrives at lab. |
| 1240 | Tower/MC/Coldplate = 53.1/31.9/196 mK, Still = 1.46 K / 0.11 mbar / 0 mW, G1/G2= 166/172 mbar, 1K Pot = 1.69 K / 55±5 mbar. |
| 1245 | MB = 57.1 % |
| 1247 | Soaked up some water on top of the LN2 cold trap dewar and started LN2 transfer. Tower temp immediately started rising by about 0.5mK/min, then dropped back down after a few minutes. |
| 1250 | Soaked up some water on the top of the fridge as well. |
| 1256 | Ended LN2 transfer, another small rise of ~1mK in tower temp after the transfer and now it is dropping at ~0.5mK/min. |
| 1305 | Zach leaves lab. |
| 2145 | MB = 41.4% |
| | Main bath seems to be boiling off about 16% faster overall since the partial warmup (and short pumpout of the cryostat vacuum jacket) |
| | Estimate that MB will hit 20% around 9:40 AM tomorrow, 15% by 12:30 pm, 10% by 3:30 pm |
