| Setup: DIB1/3/4 → 3.2 MHz filters → cables1/2/3 → DCRC55(1)/33(2)/50(3) | |
| Overnight: taking data with coincidence trigger from NaI detector, 88Y source in lead castle behind fridge | |
| 0855 | Tower/MC/Coldplate = 33.3/36.1/218 mK, Still = 1.2 K / 110 μbar, G1/G2 = 180/170 mbar, 1K Pot = 1.69 K / 24 mbar. MB = 31.1%. Boiloff rate: a little faster than slow-mode |
| 0900 | Fill LN2 coldtrap. |
| 0900 | Remove 88Y source from behind fridge and put back in safe. |
| 0955 | Put 88Y source in lead castle behind fridge. NOTE: source is now screwed onto end of the aluminum rod from the photoneutron apparatus. |
| 1026 | Return 88Y source to safe |
| 1105 | Begin LHe transfer (27.6%) |
| 1150 | Finish LHe transfer (91.8%) |
| 1205 | Released pressure from MB. |
| 1250 | Re released pressure from MB. |
| 1320 | Re released pressure from MB. |
| 1658 | Fill LN2 coldtrap full. |
| 1728 | Put 88Y source in lead castle behind fridge. NOTE: source is now screwed onto end of the aluminum rod from the photoneutron apparatus. |
| 1759 | Start sequence of 15 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 111mV high threshold 124mV and 1100V on NaI detector) using DCRCX (DCRC4) PhA. Use 700 pre-pulse samples to see if the coincident peak moves |
