| Setup: iZIP mode, DIB1/2/3 → cables → 3.2 MHz filters → DCRC55/33/50 | |
| Taking Y-Be data overnight, last flash ~ 15:10. | |
| 1608 | Place Y souce back in safe for transfer. |
| 1615 | Commence LHe transfer (29.3%). Fill LN2 cold trapp full. |
| 1635 | 1K Pot pressure at 1.5 mbar. Turn needle valve slightly, and pressure rises to 4.0 mbar and stabilizes. |
| 1712 | End LHe transfer (91.2%). |
| 1740 | Let out pressure in main bath for ~30 seconds. Place Y source back at fridge. |
| Anthony restarted data and did not record it here (as usual) so below is a reconstruction after the fact: | |
| Change trace lengths: |
| Phonon | Charge | |||
|---|---|---|---|---|
| Samples | ms | Samples | ms | |
| usual | 4096 | 3.2768 | 8192 | 3.2768 |
| new | 2048 | 1.6384 | 1024 | 0.4096 |
| note: | remember that in the ODB there is a factor-of-two error, you have to put in double the number of samples that you actually want. |
|---|
| 1825 | Start 41 series of 30min Y-Be series at -4/+4 V with FG=5/2/5, OG=3, with 1000 initial randoms, 1000 ending randoms, with 30s flash and 25 minute cooldown in between 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. Use shorter trace lengths as above. |
|---|---|
| Note: | the final series of this data set, 07160222_0811, does not have the Y source present for most of the series - it was removed Monday morning. |
