| | Setup: iZIP mode, DIB1/2/3 → cables → 3.2 MHz filters → DCRC55/33/50 |
| | Taking Cf data overnight. Last flash at 13:08 |
| 1335 | Place Cf source back in safe. |
| | There was a “Network Error” popup on the DCRC Control web page when I checked how the sequencer was doing. When reloading the MIDAS webpage, and checking the sequencer, it appears we're still running, and potentially only on series 11… So that's strange. Something must have slowed it down overnight. Stopping run in order to do the LHe transfer. |
| 1342 | Tower/MC(H35)/MC sensor/Cold Plate = 31.5/27.2/??/?? mK, Still = ?? K / 0.11 mbar, G1/G2 = 150/140 mbar, 1K Pot = 1.64 K / 6.5 mbar, Main bath = 29.2% |
| | Tweak 1K Pot needle valve open a few more degrees. P2 stabilizes at 22mbar. |
| | Fill LN2 cold trap Dewar. |
| 1355 | Commence LHe transfer (27.9%). |
| 1445 | Cease LHe transfer (89.6%). |
| 1455 | Release pressure from Main Bath. |
| 1457 | Place Strong 88-Y source in source holder w/ Be discs. |
| 1500 | Start 41 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. |
