| Setup: DIB1/3/4 → 3.2 MHz filters 3/1/2 → cable 3/1/2 → gender changer 3/1/2 → DCRC55(1)/33(2)/X(4) | |
| 0855 | Tower/MC/Coldplate = 33.4/31.0/197 mK, Still = 1.3 K / 0.110 mbar, G1/G2 = 254/239 mbar, 1K Pot = 1.695 K / 30 mbar. Main Bath = 69.6%. Boil off rate: close to slow mode (predicted level: 71.7%) |
| 0902 | Fill LN2 cold trap full. |
| 1213 | Removing south lead shield wall for NaI mounting. Notice that tower temp has a small spike and rose from 33.5 mK to 34.1 mK. Perhaps we bumped the cryostat and caused a slight touch. |
