Previous Day

  • Lab in-personnel: Himangshu
Status Run 79 beginning. Started circulation yesterday
1158 Refilled LN2 Cold Trap 1 from dewar.
1200 Tower/MC(H35)/Coldplate = 63.7/30/147 mK, Still = 1.11 K / 0.110 mbar / 0 mW, G1/G2= 70/73 mbar, 1K Pot = 45° / 1.63 K / 24 mbar. MB = 70.1%
1205 Start MIDAS. Open SQUIDTuningGUI, connect DCRC3 (donot plug the IO cable yet). Initialize DCRC, Stop Frontend, Unplug ethernet cable, connect IO cable, Start Frontend again
1215 Set up DCRCs for 2-sided 0-volt readout. Cable 2/1/3 → diverter/nothing/nothing → DCRC 1/3/4
1501 Connect DCRC3 to Cable1 and get squid tuning parameters
Cable 1: SQuid Bias: -89.8, -91.6, -74.6, -100.5 LockPoint: -8.28, -5.07, -4.21, -7.36
1520 Connect DCRC3 without IO cable, set all paramters to 0 and then reconnect with Cable 3
Cable 3: SQuid Bias: -70.4, -101.7, 0, -75.4 LockPoint: -4.24, -3.63, 0, -3.6
1557 Took IbIs rough dataset by Guilia
