- Lab in-personnel:
| Status | Run 76 ending |
|---|---|
| Setup | DCRC33(2)→HV control, NaI trigger signal → DCRCX(4) Lead/poly shield fully assembled. Boron-filled socks covering NaI detectors. PuBe removed from lab. NaI scan in progress |
| Warming up. Mixture in dump. Mixture removed from LN2 Trap 1 but it still has contaminants. Some He exchange gas in cryostat vacuum jacket and IVC. | |
| 1432 | Recovery = 700946.39 cuft (@ 14:32:41), 0.08 cuft/hr, much lower. Time to close the recovery valve. |
| 1450 | MC(Cernox)/Sorb = 168/>250 K |
| 1450 | MC(Cernox) = 167.53 K, 4.2 K/hr. Implies warming tau of 30.3 hours, should reach dew point (around 34 F) at Dec 12 23:33 |
| 2425 | MC(Cernox) = 199.34 K, 2.9 K/hr. Implies warming tau of 32.4 hours, should reach dew point (around 34 F) at Dec 13 03:38 |
| 2428 | Recovery = 700946.39 cuft (@ 04:28:53), 0.05 cuft/hr |
