Previous Day

Status Warming up. Stopped circulation yesterday. All mixture in dump. LN2 trap 2 and LHe should be checked when warm. 1K Pot needle valve open, should be closed when warm before dropping cryostat.
Setup DIB1/2/4 → 3.2 MHz filters → cable 1/2/3 → gender changer 1/2/3 → movable source controller/board with external Feedback resistor/nothing → DCRC55(1)/DCRC33(2)/DCRC50(3)
we should turn off the DAQ programs and power down the DCRCs.
0900 MC(Cernox) = 80 K
0917 Power Cycle Jiajin and Denali because both were acting weird.
0918 Restart webcamautomator using python webcamAutomater.py -device /dev/video1 -delay_min 0.3333 -total_time_hr 24 -save_images
Turns out the webcam got renamed to video0 after the reboot, run python webcamAutomater.py -device /dev/video0 -delay_min 0.3333 -total_time_hr 24 -save_images instead.
Above includes the final position in the ydelay versus position plot.
This shows the degeneracy of this y-quantity at high radius.
0931 Turn off DCRC software and power down the DCRC's.
0938 Recovery is moving incredibly slowly, increase webcam wait time to once every 5 minutes.
1241 Recovery has moved by 0.5 cuft in ~3 hours time and is currently resting at multiple of 2. This means that if there is a roll over it would have to occur in around 12 hours at the current rate. Going to restart cam with 10 minutes between pictures. Will check tomorrow if we're lucky enough to catch a roll over.
1551 MC(Cernox) = 109 K
