| | Setup: iZIP mode, DIB1/2/3 → cables → 3.2 MHz filters → DCRC55/33/50 |
| | Taking Y-Be photoneutron data overnight. Last flash at 07:20 |
| 0945 | Remove Y source from source holder and put back into safe. |
| 0950 | Tower/MC(H35)/MC sensor/Cold Plate = 31.1/26.9/41/161 mK, Still = 1.32 K / 0.12 mbar, G1/G2 = 170/160 mbar, 1K Pot = 1.72 K / 19 mbar, Main bath = 67.7% |
| 0955 | Fill LN2 cold trap Dewar. |
| 1005 | Place Ba source on fridge. |
| 1008 | Check phonon traces, all look OK |
| | will try a test series with a wider pileup rejection window: ODB / Equipment / Triggerfe2 / Settings / PileupCut (s) = 1e-4, i.e. 100 us |
| 1010 | 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 20 100 us pileup cut window. |
| 1610 | Fill LN2 cold trap full. |
| 1615 | Check phonon pulses. All look good. No obvious signs of low frequency noise. |
| 1645 | Place Ba source back in safe. Put strong 88-Y source in Be disk source holder. |
| 1650 | Start 15 30min Y-Be 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 150 us pileup cut window. |
