previous day

Current setup: iZIP mode, DIB1/2/3 → cables → 3.2 MHz filters → → DCRC55/33/50.
Overnight: taking Cf data last night, last flash at 22:35. Bath is rather low: 1 K Pot temp and pressure have been falling, starting at about 6:20.
0825 Fill LN cold trap Dewar
0830 Tower/MC(H35)/MC sensor/Cold Plate = 31.0/25.4/45.1/159 mK, Still = 1.34 K / 0.080 mbar, G1/G2 = 175 mbar, 1K Pot = 1.70 K / 18 mbar, Main bath = 6.6%
0850 Start LHe transfer (6.2%).
1025 Cease LHe transfer (93.4%).
1600 SQUID tuning MIDAS program (see Pulse Viewing with MIDAS for instructions) was successfully used to view pulses and apply phonon settings.
1620 Use MIDAS to change trigger thresholds to the values set on 2015/09/15.
1630 Use MIDAS to apply -/+4 V charge bias through ODB. Assume that Qinner and Qouter values are applied correctly by MIDAS and do not need to be reversed, as is the case for Labview. Charge pulses were then checked using the MIDAS SQUID tuning GUI, and appeared normal.
1640 Use FlashandFlash from the DCRC_UI page to flash the detectors for 0.1s On and 5s off for 30s total.
1650 Fill LN2 cold trap full.
1700 Set 'Data write' to yes in MIDAS ODB/Logger in preparation for data taking. Start data run with MIDAS.
