| 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) Lead/poly shield fully assembled. Boron-filled socks covering NaI detectors. PuBe source behind lead wall. NaI trigger window -t10760 -T15760 (7.6-11.2 MeV) |
| 0925 | MC = 29.1 mK, HV = -197.30 V, Vtest = -29.2 mV |
| 0926 | Start -197.3 V PuBe data series 8 min long, with 1000 initial randoms, 5 Hz in-run randoms, trigger on DCRC3pD threshold 10 (Si-triggered). Start series with the Start Button. |
| 0935 | Start -197.3 V PuBe data series 273 min long (only 168 good dumps, see below), with 1000 initial randoms, 5 Hz in-run randoms, trigger on DCRC4pA threshold 20 (NaI-triggered). Start series with the Start Button. |
| 1224 | Some DAQ problem occurred during Dump 168, all dumps after that are empty |
| 1410 | Trouble stopping the series because of DAQ problem. Turning off DAQ programs finally ended the MIDAS run. |
| 1415 | Start -197.3 V PuBe data series 9 min long, with 1000 initial randoms, 5 Hz in-run randoms, trigger on DCRC3pD threshold 10 (Si-triggered). Start series with the Start Button. |
| 1420 | MC = 29.2 mK, HV = -197.31 V, Vtest = -29.5 mV |
| 1425 | Dial HV down to 0V |
| 1510 | MC/Coldplate = 29.1/155 mK, Still = 1.13 K / 0.095 mbar / 0 mW, G1/G2 = 100/92 mbar, 1K Pot = 60° / 1.55 K / 7.5±0.5 mbar, MB = 27.7%. |
| 1510 | Closed off LN2 purge to build up pressure |
| 1523 | Begin LHe transfer @ MB = 27.0% |
| 1607 | Ended LHe transfer @ MB = 91.5% |
| 1638 | Filled LN2 cold trap bath, set up purge |
| Didn't fill LN2 all the way since it was flowing really slow at the end | |
| 1717 | Start 0 V PuBe data series 50 min long, with 1000 initial randoms, 5 Hz in-run randoms, trigger on DCRC3pD threshold 10 (Si-triggered). Start series with the Start Button. |
| Let's take some NaI-triggered data at 0V | |
| 1807 | Start 0 V PuBe data series 213 min long (only first 204 dumps good), with 1000 initial randoms, 5 Hz in-run randoms, trigger on DCRC4pA threshold 20 (NaI-triggered). Start series with the Start Button. |
| 2134 | Tower_FE apparently crashed at end of Dump 204, all dumps after that are empty. |
| 2144 | Start 0 V PuBe data series 2052 min (34 hours) long, with 1000 initial randoms, 5 Hz in-run randoms, trigger on DCRC4pA threshold 20 (NaI-triggered). Start series with the Start Button. |
