1000 Filled LN2 cold trap.
Stopped flashing detector from Dibs 1 and 2. The temperature while flashing was 127 mK. I thought it was 160 mK the day before.
Fed Cricket 4 pellets.
1015 Noticed that both DCRC32 and 33 are unpowered. Not sure why this is the case.
1050 Boards are all powered. Mixing chamber temperature is 51.2 mK. Pressures in G1 and G2 are 55 mbar and 71 mbar, respectively.
Now zapping SQUIDs.
1414 Begin charge breakdown tests.
1817 Fed Cricket 4 pellets.
1830 Conducted charge breakdown tests across the crystal where Dib 1 is positively biased and Dib 2 is negatively biased. No charge breakdown was detected. Hm!
