| | 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 at standard position |
| | DCRCs on overnight taking bg data. |
| 0805 | Tower/MC/Coldplate = 41.7/36.0/169 mK, Still = 1.50 K / 0.075 mbar, G1/G2 = 210/195 mbar, 1K Pot = 1.54 K / 5.0 mbar, MB = 67.2%
Boiloff rate is good. |
| 0810 | Fill LN2 cold trap bath |
| 1135 | Made adapter to pump out broken cold trap. Pumping with scroll pump, pressure at 1.9e-1 mbar |
| 1144 | Cold trap pressure 7.9e-2 mbar. Close off scroll pump. |
| 1145 | Cold trap pressure 5.4e-1 mbar. |
| 1147 | CPT = 6.3e-1 mbar |
| 1148 | CTP = 7.4e-1 mbar |
| 1149 | CTP = 8.6e-1 mbar |
| 1154 | CTP = 1 mbar |
| 1155 | Start 2 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. |
| 1410 | Start 30min background series at -6/+6 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. |
| 1542 | Start 30min background series at -6/+6 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. |
| 1635 | Made new adapter for the cold trap Dewar pumpout fitting. Pump on cold trap dewar jacket, after a few minutes = 0.16 mbar. |
| 1645 | Cold trap dewar jacket = 0.063 mbar. Close off valve to scroll pump. |
| 1648 | Cold trap dewar jacket = 0.40 mbar. |
| 1655 | Cold trap dewar jacket = 0.40 mbar. Looks pretty good. |
| 1700 | Try pumping with the plunger and plug in place. This seems to work - was able to release plug, then it was stuck as it should be. Was able to pull it out with a little effort and let air back in. |
| 1715 | Start pumping out LN2 cold trap dewar jacket |
| 1740 | Scroll pump pressure = 0.040 mbar as it pumps the LN2 cold trap dewar jacket. Close the pump plug and remove pumpout adapter. |
