| Setup: DIB1/3/4 → 3.2 MHz filters → cables 1,2,3 → HV board inputs 1,3,2 → HV board outputs 1,2 → DCRC55(1)/50(3) | |
| HV at 0 V overnight | |
| 0805 | Tower/MC/Coldplate = 33.4/34.7/223 mK, Still = 1.3 K / 110 μbar, G1/G2 = 175/150 mbar, 1K Pot = 1.71 K / 32 mbar. MB = 29.7%. Boiloff rate: |
| 0810 | Fill LN2 cold trap bath. |
| 0810 | Remove 88Y source from fridge, replace in safe |
| 0930 | Lower PuBe neutron source into shield to activate detector. Scheduled to remove it at 13:00 |
| 1058 | Commence LHe transfer (24.3%). |
| 1158 | Finish LHe transfer (86.6%) |
| 1208 | Release pressure from main bath. |
| 1320 | Remove PuBe neutron souce from cryostat. |
| 1400 | 0V 100ms randoms for muon |
| 1403 | Release pressure from main bath. |
| 1555 | Event rate is elevated since the activation. Counted 110 events in 1 second = 110 Hz. Hopefully some of this is short-lived stuff. |
| 1615 | 60V 100ms randoms for muon |
| 1710 | Fill LN2 coldtrap full. |
