| 1000 | Fill N2 cold trap full. |
| | Tower temperature stable at 155 mK. Pressure in G2 high at 180 mbar. |
| 1400 | Tower temperature seems to rise. Could this be due to the DCRC boards? |
| 1620 | Tower temperature rising. Helium level 5.8%. Perform LHe transfer. |
| 1730 | LHe transfer complete, helium level 96.1%. Tower temperature dropping. |
| 1800 | Tower temperature reaches 165 mK. Things seem to be back to normal. |
| 2000 | Tower temperature increasing inexplicably. Pressure in G2 is 96 mbar. Turn on Still (5.0 mW) to increase circulation and increase needle valve to 1 K pot. Increase causes 1 K pot temperature to rise from 1.6 K to 1.7 K. Why? |
| 2015 | Too early to turn on Still: tower temperature increases. Turn Still off. Switch to nitrogen cold trap 2 as cold trap 1 might be dirty. |
| 2130 | Tower temperature hovering around 220-230 mK. Pressure in G2 119 mbar. Temperature of 1 K pot is 1.7 K, and exhaust line shows a relatively high pressure of 50 mbar. Cold trap 2 seems to be helping somewhat. Perhaps cold trap 1 needs a more thorough clean. |
| 2330 | Base temperature still rising. Noticed helium trap was loose, so tightened it. This led to a reduction in temperature. I have no idea why. |
