| 1240 | DAQ stopped at 0152 last night. Got in and found computer had rebooted, pumps were off and all valves on IGH were closed. As a result, tower temperature is 1.3 K. Suspect there was a power failure in the early morning hours, but not sure how DAQ computer turned itself back on… |
| | Restart 1 K pot. |
| 1250 | Fill N2 cold trap full. Mixture is already condensed inside the fridge, so restart circulation slowly. |
| 1300 | Reset timing link on boards. Had to turn FET heater on when rebooting DCRC32. Pulses look good. Not sure if detectors had been under bias during the night, but they aren't under anymore. It may be best to flash the detector for a few hours once we're at base temperature to ensure they are neutralised. |
| 1315 | Windows Updates keeps asking to restart DAQ machine. Will do so now while fridge cools. |
| 1345 | Valve 6 fully open. Cooldown is very slow. There is still plenty of cooling power left in the fridge and the tower is getting colder, but tower temperature is 770 mK. Temperature of 1 K pot is a little low at 1.5 K. Open needle valve a tad to increase 1 K pot temperature to 1.6 K. |
| 1400 | Much better. Tower temperature 300 mK and dropping fast. |
| 1445 | Tower temperature has stabilised at 85 mK. Start flashing detector. |
| 1955 | Stop flashing detector. |
