| Status | Run 75 in progress |
|---|---|
| Setup | Tower Faces 5/3/2 → Cables 2/1/3 → nothing/diverter_board/nothing → DCRC55(1)/DCRC50(3)/DCRCx(4) Lead shield in place. Am Source y = 39.99 mm |
| 0906 | Goldman/Tower/MC(H35)/Coldplate = 41.4/74/34.3/184 mK, Still = 1.44 K / 0.110 mbar / 0 mW, G1/G2= 259/252.8 mbar, 1K Pot = 1.60 K / 15±1 mbar, MB = 41.0%. |
| 0915 | Fill LN2 cold trap bath |
| 1100 | Goldman = 42.0 mK. Set QET biases to target dP/dI=1.0 uV and adjust driver offsets so baselines ~ -0.9 V |
| 1107 | Start 0V data series, 38 min long, with 1000 initial randoms, no in-run randoms, trigger on DCRC3pB threshold 10. Start series with the Start Button. |
| 1110 | Goldman = 41.9 mK. Readjust QET biases |
| 1115 | Goldman = 41.8 mK. Readjust QET biases |
| 1131 | Goldman = 41.7 mK. Readjust QET biases |
| 1135 | Goldman = 41.8 mK. Readjust QET biases |
| 1141 | Goldman = 41.7 mK. Readjust QET biases |
| 1150 | Zap SQUIDs (one channel looked a little messed up) |
| 1429 | Begin LHe transfer @ MB = 33.2% |
| 1501 | End LHe transfer @ MB = 89.3% |
