| | Current setup: iZIP mode, DIB1/2/3 → cables → 3.2 MHz filters → DCRC55/33/50. |
| | Overnight: Taking data, no external source. Last flash at 8:40. Tower temperature stable. |
| 1415 | Fill LN2 cold trap full. |
| 1419 | Commence LHe transfer (13.4%). |
| 1445 | Tower/MC(H35)/MC sensor/Cold Plate = 31.1/25.7/41.1/156 mK, Still = 1.32 K / 0.11 mbar, G1/G2 = 175/155 mbar, 1K Pot = 1.71 K / 22 mbar |
| 1500 | DIB1 pB flatline, needed a relock |
| 1505 | Place Cf source at top of shield on fridge |
| 1547 | End LHe transfer (89.3%). |
| 1548 | No obvious low frequency noise patterns in phonon channels |
| 1550 | Start Cf data, 50 series. Phonon thresholds same as yesterday. Now-standard settings: -4V/+4V, output gain setting 3, frontend gain 5/2/5. After randoms events rate is about 12 Hz. |
| note: | Error in the metadata. I tried changing the word “background” to “Cf” in the MultiDAQ input field, while MultiDAQ was not in run mode, but when I started DAQDAQ it reverted to “background”. |
