Status	Run 75 in progress
Setup	Tower Faces 5/3/2 → Cables 2/1/3 → nothing/diverter_board/nothing → DCRC55(1)/DCRC50(3)/DCRCx(4) Lead shield in place. Am Source y = 20.01 mm
1335	Establish communication with Arduino. This causes a temperature spike because I'm working remotely so I didn't turn off the GwINSTEK power supply output. Goldman spikes to 0.47 K then cools.
1340	Set Dwell to 40 ms
1350	Do mvNwait -4steps×152 times, 40 second wait, with dwell = 40 and power = 6.8 V. (Around 5.93 mm/hour) This sequence will take 1hr41min20sec and will move the source a total distance of 10.02 mm ending at y = 30.03 mm. Should end at 3:31 pm. Temperature settles at average 0.51 K, 40-second period peak-to-peak 0.05 K oscillations. Longer period beats, similar to last move sequence. Beat period is a little over 8 minutes or 12 moves, which is 1 full rotation
1600	Goldman = 80 mK and cooling
1605	Turn on DCRC1 LEDs with rep rate reduced from 5000 to 500. Turn off LEDs after 3 minutes. Goldman peaked at 1.29 K.
1710	Goldman = 51 mK and cooling. Check the channels, unrail some of them

1749	Goldman/Tower/MC(H35)/Coldplate = 49.1/153/34.2/161 mK, Still = 1.13 K / 0.110 mbar / 0 mW, G1/G2= 255/225 mbar, 1K Pot = 1.61 K / 15±1 mbar, MB = 56.3%.
1755	Fill LN2 cold trap bath
