| 1523 | Filled LN2 cold trap. |
| 1530 | Noticed that 1K Pot and Tower temperature were quite high (~ 2 K). G1 and G2 were fluctuating heavily (going from 400 mbar to < 200 mbar, then up to 800 mbar, etc). |
| | Looking through temperature history today, found that at 1330 temperature increased from 500 mk to 1.8 K |
| | Seems that a lot of mix isn't in the fridge - high pressure in P1. |
| | Stopped circulation. Will recondense mixture. |
| | Closed V6. |
| | Waited for pressures in G1/G2 to lower < 100 mbar - opened V9 to pull out mix that was in dump. |
| | When G1 and G2 are ~ 70-80 mbar, most of mix is probably condensed |
| | Closed V9 |
| | Opened V6 slowly. Note that P1 has dropped- most of mix is no longer outside of fridge |
| | Pulled out more mix from dump - opened V14 (P1 increased again) |
| | Monitored G1/G2 to make sure they were < 200 mbar. Opened/closed V6 accordingly |
| | Note: Auto-circulation VI was still on when detectors were flashed. This should be turned off once circulation has fully commenced because this VI monitors pressures in G1/G2 and closes/opens V6 to maintain pressures < 200 mbar. Flashing detectors intereferes with this. |
| 1650 | Opened V6 fully. |
| 1730 | G1: 82 mbar , G2: 80 mbar , Tower: 128 mK |
| 1810 | Begin LHe transfer (~8%). |
| 1840 | End LHe transfer (79.7%). |
| | G1: 75.5 mbar , G2: 71.6 mbar, Tower: 79.2 mK |
| 2010 | Tower temperature is very eratic. It has risen to 115 mK, and is still going up. |
| | Switch to mixing chamber thermometer, use H35 curve. Mixing chamber is at 92 mK. Doesn't look like a themometetry problem. |
| | Monitor mixing chamber temperature overnight. |
