| | Status: circulating overnight, base temperature, nothing plugged in to the DIBs |
| 0820 | Tower/MC(H35)/MC sensor/Cold Plate = 41.3/28.4/42.4/155 mK, Still = 1.02 K / 0.095 mbar, G1/G2 = 150/140 mbar, 1K Pot = 1.59 K / 5.5 mbar, Main bath = 36.5% |
| | Tower temperature is still decreasing very slowly. Base doesn't seem quite as cold as the last run, MC or Tower. 1K Pot is running low. G1/G2 have been decreasing overnight from about 200 mbar. |
| 0830 | Open 1KPot needle valve about 5 degrees wider. 1KPot → 1.70 K / 17 mbar |
| 0840 | Fill LN2 cold trap Dewar |
| | Tower temperature is decreasing a bit, maybe in response to 1KPot adjustment? |
| 0854 | Try heating still by 5 mW. Still P increases to 0.18 mbar, G1/G2 increase to 240/220 mbar. Tower temp spikes then falls, settling near its previous value of 40.7 mK. |
| 0925 | Turn off still heater |
| 0930 | Begin assembling shield |
| 1015 | 1KPot pressure had fallen down to 8 mbar - open needle valve 5 degrees further. |
| 1200 | Tower/MC(H35) = 40.7/28.0 mK, Still = 0.10 mbar, G1/G2 = 190/170 mbar, 1K Pot = 1.68 K / 13 mbar, Main bath = 29.5% |
| 1330 | Finish assembling shield |
| 1425 | Plug in DCRCs same as last run: iZIP mode, DIB1/2/3 → cables → 3.2 MHz filters → DCRC55/33/50. Establish communication using telnet on jiajin, e.g. telnet 131.225.52.95 5000 |
| 1435 | Start LHe transfer at 21.5% |
| 1450 | Start the three DAQ programs on the MIDAS webpage |
| 1500 | Try zapping with MIDAS. Doesn't look like it worked - after 5 minutes no change in Tower temperature or Still pressure. |
| 1540 | End LHe transfer (93.1%). |
| 1635 | Fill LN2 cold trap full. |
| 1817 | After some tests on MIDAS, set to flash overnight. |
