- Lab in-personnel: Matt, Giulia
| Status | Run 76 in progress |
|---|---|
| Setup | Cables 2/3/1 → diverter/nothing/nothing → Side2-readout HV CONN 1/3/2 → HV 1(L)/2(R) → DCRC50(3)/DCRC55(1), DCRC33(2)→HV control, NaI trigger signal → DCRCX(4) |
| 1030 | MC/Coldplate = 28.2/146 mK, Still = 1.09 K / 0.100 mbar / 0 mW, G1/G2 = 136/131 mbar, 1K Pot = 45° / 1.55 K / 8.5±0.5 mbar, MB = 43.6% |
| 1040 | Move PuBe source in paraffin drum into K100 lab. Place drum behind lead wall on floor. Take NaI trigger scan data. |
| 1110 | Raise paraffin drum up onto wood platform, 12cm above floor. Take NaI trigger scan data. |
| We'll take data like yesterday with PuBe present, but this time elevated - yesterday it was on the floor. | |
| 1110 | Check phonon channels - look good. |
| 1114 | Start 0 V PuBe data series 21 min long, with 1000 initial randoms, 5 Hz in-run randoms, trigger on DCRC3pD threshold 10. Start series with the Start Button. |
| 1135 | Remove PuBe from lab, return to PAN434 |
| 1320 | Fill LN2 cold trap bath. |
| 1507 | Begin LHe transfer @ MB = 37.6% |
| 1555 | End LHe transfer @ MB = 95.6% |
