| | Setup: DIB1/3/4 → 3.2 MHz filters 3/1/2 → cable 3/1/2 →gender changer 3/1/2 → HVConn 1/3/2 → HV 1/2 → DCRC55/DCRC33 |
| | Took data overnight, HV = 10 V. |
| 0855 | HV=9.99V, Vleak = 0.2 mV, V_crystal = 9.91 V |
| 0855 | Tower = 33.7 mK, Main bath = 28.8% |
| 0900 | Fill LN2 cold trap bath |
| 1111 | Tower/MC/Coldplate = 33.7/31.2/187mK, Still = 1.16 K / 0.110 mbar, G1/G2 = 250/211 mbar, 1K Pot = 1.692 K / 28 mbar, Main bath = 24.9%. Boil off rate: nearly slow mode (predicted level: 25.1%). |
| 1130 | Start LHe transfer (MB = 23.9%). Pressure lowered to 1.5 psi. |
| 1220 | End LHe transfer (MB = 93.2%) |
| 1556 | Attempt to measure IbIs of DIB1 PB. However, it is currently -ADC railed beyond Driver Offset range. Re-locking SQUID does not help, nor does snapping. |
| 1601 | Can get trace to show by reducing FEgain to 3, driver offset = -2 |
| 1608 | The FEgain seems to have a strange effect here. Increasing it from 4 to 5 makes the traces very noisy, but leaves the baseline alone. Increasing it further to 6 cleans up the noise, but pulls the baseline down considerably. Further increasing the FEgain to 7 -ADC rails the channel. |
