| | Setup: DIB1/3/4 → SL 27/19/20 → 3.2 MHz filters → cables 2,1,3 → HV board inputs 1,3,2 → HV board outputs 1,2 → DCRC55(1)/50(3). |
| 1000 | MIDAS got stuck last night. Restart MIDAS and DAQ programs. |
| 1003 | Begin IbIs data sequence on DCRC3pD with HV=0V from 750 to 400 uA in -0.5 uA steps, 3 seconds of data per step |
| | Sequence continued to completion. |
| 1157 | Tower/MC/Coldplate = 29.1/27.1/153 mK, Still = 1.27 K / 0.110 mbar, G1/G2 = 150/140 mbar, 1K Pot = 1.66 K / 38 mbar, MB = 19.9% |
| 1159 | Fill LN2 cold trap. |
| 1209 | Start LHe transfer (MB = 19.6%) |
| 1259 | Pause LHe transfer, dewar ran empty. MB = 48.7% |
| 1308 | Resume LHe transfer with new dewar. |
| 1310 | Stop DAQ programs and restart MIDAS, then restart programs |
| 1400 | End LHe transfer (MB = 87.6%) |
| 1429 | Begin IbIs data sequence on DCRC3pC with HV=0V from 750 to 400 uA in -0.5 uA steps, 3 seconds of data per step |
| | This sequence got stuck again, at the same place as when I tried it yesterday: last data file was at 459.0 uA at 16:21. I'll write a new sequence with a different range (for this channel 400 uA may not be low enough anyway, 430 uA was the operating value. |
| 2050 | Kill MIDAS, then restart it. Then start the DAQ programs. |
| 2057 | Try starting sequence but run into error because identically-named file already exists in /livedata. Create folder /byseries/07171119_2500 and put today's files there. |
| 2106 | Begin IbIs data sequence on DCRC3pC with HV=0V from 600 to 300 uA in -0.5 uA steps, 3 seconds of data per step |
| 2200 | Sequence got past 459.0 uA, that's good. Still going. |
| | Moved the DCRC3pD files and the first attempt (14:29) on DCRC3pC to /byseries/07171119_2500. Moved the second, complete attempt on DCRC3pC to /byseries/07171119_2600. |
