| 0919 | Tower = 25.6 mK |
| 0920 | Sequence still running. Current series is -4/+4 V, started at 07170722_0845. Adjust DCRC1 q[0] trigger = 150. |
| 0923 | Adjust DCRC1 q[0] trigger = 200. |
| | Triggering looked good on series 07170722_0719, but went back to the crazy triggering mode for 07170722_0845. I had turned on the SQUIDtuningGUI to look in on 07170722_0719, but it finished fine with normal triggering. Maybe having it open (though inactive) when 07170722_0845 started caused this? Closing the SQUIDtuningGUI during the run doesn't help. I'll let the sequence continue with the GUI closed and see if it starts working again on the next series. |
| 1021 | Indeed, the -5/5 V series that started at 1011 seems to be triggering properly (checked via batviewer). It seems batviewer can interfere with triggering somehow. |
| | Reduce DCRC1 q[0] trigger = 100. |
| 1029 | Oops, maybe that was too low, triggering on noise. Raise DCRC1 q[0] trigger = 200. |
| 1032 | That looks better (dump 19), leave it at 200 for the remainder |
| 1258 | Fill LN2 cold trap full. |
