| | Setup: iZIP mode, DIB1/2/3 → cables → 3.2 MHz filters → DCRC55/33/50 |
| | Taking Y-Be photoneutron data over weekend. Last flash at 06:55 |
| 0900 | Remove Y source from source holder and put back into safe. |
| 0905 | Tower/MC(H35)/MC sensor/Cold Plate = 31.1/27.0/39/149 mK, Still = 1.11 K / 0.12 mbar, G1/G2 = 170/155 mbar, 1K Pot = 1.73 K / 19 mbar, Main bath = 29.3% |
| 0915 | Fill LN2 cold trap Dewar. |
| 1020 | Set DIB1 Qi/Qo threshold values to 210ADC bins each. |
| 1025 | Place Ba source on fridge. Find that the Ba source was inside the fridge shield all night (it was never put away). This means the data we took overnight had Ba and Y-Be sources present. |
| 1027 | Start 1 30min Ba series at -4/+4V with FG=5/2/5, OG=3, with 1000 initial randoms, 1000 ending randoms, 30s flash and 25 minute cooldown before series. Trigger on DIB1 phA with threshold of 20ADC bins and DIB1 qInner&qOuter each with threshold 210 ADC bins, with 20 us pileup cut window. |
| 1445 | Start LHe transfer (17.3%). |
| 1545 | End LHe transfer (89.8%). |
| 1620 | Let pressure out of cryostat by removing stopper for about 30 seconds. |
| 1645 | Check phonon traces, all look OK |
| 1654 | Fill LN2 cold trap. |
| 1700 | Ba source back in safe. Take out Y-88 source and place in shield. |
| 1800 | Anthony started 30min Y-Be series to end at 8:00 at -4/+4V with FG=5/2/5, OG=3, with 1000 initial randoms, 1000 ending randoms, 30s flash and 25 minute cooldown before series. Trigger on DIB1 phA with threshold of 20ADC bins and DIB1 qInner&qOuter each with threshold 210 ADC bins, with 20 us pileup cut window. |
