| 1200 | Fill LN2 cold trap bath. |
| 1232 | Tower/MC/Coldplate = 33.3/30.8/194 mK, Still = 1.3 K / 0.120 mbar, G1/G2 = 249/238 mbar, 1K Pot = 1.689 K / 28 mbar. MB = 67.8%. Boil off rate: close to slow mode (predicted level: 69.7%). |
| 1327 | Complete IbIs on DCRC4PB/S2PF. Was able to get a full curve, but had to move slowly down the transition to keep from falling into sc early. I also noticed a discontinuity in the curve when stepping down by 0.25uA. When going from Ib = xxx.25 to xxx.0, (corrected values are generally something like xxx.26 and xxx.01) the Vout value at xxx.0 would rarely fall as much as expected given the surrounding curve. This can be seen in the plot below. |
