| Status | Run 77 in progress |
|---|---|
| Setup | Cable 2/1/3 → diverter/nothing/nothing → DCRC50(3)/DCRC55(1)/DCRCX(4) |
| 0940 | Start MIDAS. DCRCs are setup for 2-sided 0-volt readout. |
| 0942 | Turned on DCRC1 and the DAQ programs. |
| 0949 | Turned on Pulse Viewer. Can see noise traces on PA, PB, PC and PD on DCRC1. We haven't set the SQUIDS or QET biases at this time. |
| 0958 | Turned on DCRC3 and the DAQ programs. Need to restart the towerfe and triggerfe programs multiple times to turned them on simultaneously . All channels seems to be railing. |
| 1007 | Turned on DCRC4 and the DAQ programs. Need to restart the towerfe and triggerfe programs multiple times to turned them on simultaneously . PA and PC shows noise traces but PB and PD seems to be railing. Note: PD was not showing high resistance at BOB as well |
| 1145 | Tower(RoX)/Tower(U28)/MC(H35)/Coldplate = 70.0/55.0/59.4/172.9 mK, Still(P1) = 1.29 K / 0.13 mbar / 0 mW, G1/G2 = 144.4/142.5 mbar, 1K Pot(P2) = 35° / 1.62 K / 22 mbar, MB = 68.3% |
| 1159 | Tower(RoX)/Tower(U28)/MC(H35)/Coldplate = 70.0/60.1/55.3/172.9 mK, Still(P1) = 1.28 K / 0.13 mbar / 0 mW, G1/G2 = 143.9/142.5 mbar, 1K Pot(P2) = 35° / 1.62 K / 20 mbar, MB = 67.9% |
| 1306 | Seeing large spikes in MC temp, up to 200mK earlier, seems we will have to do the same 10K pumpouts as last run |
| 1308 | Fill LN2 cold trap dewar from the 25L bomb dewar (via the 5L dewar), the bomb dewar is empty now. |
| 1447 | Switching to Tower thermometers to see if unplugging the DCRCs have any effect on the temperature. Tower(U28) = 64.2 mK |
| 1458 | A few min after unplugging the dcrcs, Tower(U28) = 54.2 mK (note that we are on the falling side of the temperature spikes |
| 1459 | temp bumped up a small amount (1mK) after plugging in dcrc3, not much change after plugging in dcrc1 and 4 |
| 1504 | Seeing a rise (few mK) forming a bit after running dcrc3 |
| 1506 | DCRC3 all channels seems flat and DCRC4 channel PB and PD seems flat. Doing an electrical check at the BOB to investigate this further |
