| | Setup: iZIP mode, DIB1/2/3 → cables → 3.2 MHz filters → DCRC55(1)/33(2)/50(3), Tower has been cooled below Al transition with mu-metal shield 45.9 cm below standard position |
| | DCRCs on overnight taking bg data. Tower temperature quite stable between flashes. |
| 1008 | Tower/MC/Coldplate = 42.6/36.4/165 mK, Still = 1.47 K / 0.12 mbar, G1/G2 = 178/170 mbar, 1K Pot = 1.44 K / 2.0 mbar, MB = 71.7% |
| | Boiloff rate is good, so yesterday's pressure release pattern was adequate: once 5 minutes after the fill and once 40 minutes after. |
| | Filled LN2 cold trap and opened 1K pot an additional 10 degrees. |
| 1014 | relocked railed channels: DCRC1 PB, DCRC3 PD |
| 1019 | Start 19 hours of 30min background series at +4/-4 V with FG=5/2/5, OG=8/3/8, with 1000 initial randoms, 1000 ending randoms, with 30s flash and 25 minute cooldown between series. Trigger on DIB1 phA with threshold of 30ADC bins, with 150 us pileup cut window. |
| 1024 | Tower temp peaks at 250mK during flash. 1K pot pressure=20mbar. |
