Previous Day

Status Fourth day of circulation. DCRCs on overnight. HPGe crystal data taking overnight.
Setup: iZIP mode, DIB1/2/3 → cables → 3.2 MHz filters → DCRC55(1)/33(2)/50(3)
1412 Fill LN2 cold trap full.
Tower/MC/Coldplate = 37/33/144 mK, Still = 0 mW (off) / 1.16 K / 0.090 mbar, G1/G2 = 129/122 mbar, 1K Pot = 1.42 K / 2.4 mbar.
1417 Since 1K Pot is pretty low, open needle valve a bit. Give some time to settle.
1418 Stop HPGe crystal run. Slowly power down the crystal and turn off power supply and crate, but keep DCRC powered so its easier to setup for data taking next time.
1424 It has been several minutes, and the 1K Pot has settled to 1.69 K / 34 mbar.
1430 At time of leaving, He level at 57.3%.
