- Lab in-personnel: Matt
| 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 = 30.03 mm |
| 1730 | Take some mini-IbIs at Goldman = 44.8 mK. Then set QET biases to target dP/dI=1.0 uV and adjust driver offsets so baselines ~ -0.9 V |
| 1746 | Start 0V data series, 25 min long, with 1000 initial randoms, no in-run randoms, trigger on DCRC3pB threshold 10. Start series with the Start Button. |
| 1750 | Goldman = 44.7 mK |
| 1755 | Goldman/Tower/MC(H35)/Coldplate = 44.7/121/33.5/160 mK, Still = 1.13 K / 0.110 mbar / 0 mW, G1/G2= 254/242 mbar, 1K Pot = 1.61 K / 15±1 mbar, MB = 20.3%. |
| 1813 | Begin LHe transfer @ MB = 19.8% |
| 1820 | Fill LN2 cold trap bath |
| 1852 | End LHe transfer @ MB = 90.4% |
