Previous Day

Setup: DIB1/3/4 → 3.2 MHz filters → cables1/2/3 → DCRC55(1)/33(2)/50(3)
1115 Tower/MC/Coldplate = 33.1/36.2/225 mK, Still = 1.3 K / 110 μbar, G1/G2 = 175/153 mbar, 1K Pot = 1.68 K / 22 mbar. MB = 24.2%.
1115 Put Y-88 source in safe. Fill LN2 coldtrap.
1125 Commence LHe transfer (22.4%).
1215 End LHe transfer (92.0%).
1224 Released pressure from MB.
1300 Re released pressure from MB.
1908 put 88Y source back near fridge and adjust position to be closer
1920 took several test series and had an MHTTPD crash when trying to start a sequence of data taking, restart DAQ and try the sequence again, the sequence was with a modified Dont_You_Dare_Flash_andTake.msl
1934 Start sequence of 36 one-hour data series of 0V data with Frontend Gain = 5/2/5, OG = 8/3/8, with 2000 beginning randoms (because of increased pileup from higher source rate), with no flashing in between series, triggered with NaI coincidence setup (low threshold 100mV high threshold 135mV and 1100V on NaI detector) using DCRCX (DCRC4) PhA.
