  • Lab in-personnel: Anthony, Kitty, Matt, Derek
Status Run 76 in progress
Setup Cable 2/1/3 → diverter/nothing/nothing → DCRC50(3)/DCRC55(1)/DCRCX(4)
0840 MC/Coldplate = 28.8/140 mK, Still = 1.12 K / 0.130 mbar / 0 mW, G1/G2= 178/166 mbar, 1K Pot = 18° / 1.66 K / 27±2 mbar
0935 Do mini-IbIs on DCRC1pA/pB to find QET bias for dP/dI = 0.7 uV
1110 Do mini-IbIs on DCRC1pC/pD to find QET bias for dP/dI = 0.7 uV
1140 Do mini-IbIs on DCRC3pA/pB to find QET bias for dP/dI = 0.7 uV
1350 Attempting the same on DCRC3pC. But the lowest dP/dI before it falls into superconducting is 0.95 uV. And there are a lot of electrothermal oscillations near the bottom of the transition. Set to dP/dI = 1.02 uV.
1405 Do mini-IbIs on DCRC3pD to find QET bias for dP/dI = 0.7 uV
1435 Do mini-IbIs on DCRC4pA/B to find QET bias for dP/dI = 0.7 uV
1510 Do mini-IbIs on DCRC4pC/D to find QET bias for dP/dI = 0.7 uV
1510 MC = 28.7
1525 Redo mini-IbIs on DCRC1pB to find QET bias for dP/dI = 0.7 uV, and extend so that we can also set to 1.0 uV
1536 Begin LHe transfer @ MB = 19.8%
1624 End LHe transfer @ MB = 93.1%
1630 Fill LN2 cold trap bath
