| Setup: DIB1/3/4 → 3.2 MHz filters → cables → DCRC55(1)/33(2)/50(3) |
|
| 1246 | Tower temp @34 mK, 1K pot pressure ~4.5mbar, 1Kpot temp=1.5K, G1/G2=115/11mbar. MB=63.8%. 1K Pot temperature has gotten less stable over time, with oscillations between ~1.52 to 1.58 K since about 8 am. Boiloff rate is good, slightly faster than slow-mode. Yesterday released pressure at 13 and 52 minutes after the fill. |
| Fill LN2 cold trap full. | |
| 1250 | Tweak 1K Pot, give time to settle. |
| 1255 | Place Cf source (in poly container) at detector level of fridge for overnight activation. |
| 1330 | After getting distracted and giving the 1K Pot LOTS of time to settle, 1K pot pressure 80mbar, 1Kpot temp=1.76K. Both temperature and pressure are still slowly dropping, but this will hopefully last till tomorrow morning. |
