| Setup | Tower Faces 5/3/2 → Cables 2/1/3 → nothing/diverter_board/nothing → DCRC55(1)/DCRC50(3)/DCRCx(4) |
| 1110 | Goldman/Tower/MC/Coldplate = 53.4/154/37.1/222 mK, Still = 1.7 K / 0.130 mbar / 0 mW, G1/G2= 171/159 mbar, 1K Pot = 1.64 K / 26±2 mbar. MB = 25.6% |
| | Coldplate and Still thermometers are still reading high, still thermometer reading not very stable. |
| 1115 | Fill LN2 cold trap bath. |
| 1130 | Start MIDAS series with all 3 DCRCs enabled, see pulses in all the working channels (all but DCRC3pD). |
| 1135 | Restart DAQ programs with only DCRC1 enabled. |
| 1140 | Adjust DCRC1pB driver offset so that IbIs peak (QET bias around 350) is near top of output scale. |
| 1146 | Start automated IbIs on DCRC1pB. 500 to 200 uA step -2. |
| | Make new directory in /byseries and move the QB_scan files from /livedata to the new directory. |
| 1225 | Adjust DCRC1pC driver offset so that IbIs peak (QET bias around 335) is near top of output scale. |
| 1235 | Write new sequence IbIs_loop_Generic rather than a different sequence for every channel. Need to reset DCRC*p* and QETbias (ua)[*] (4 places), and initial bias, loop n, and final reset bias. |
| 1239 | Start automated IbIs on DCRC1pC. 500 to 200 uA step -2. |
| 1310 | Make new directory in /byseries and move the QB_scan files from /livedata to the new directory. |
| 1315 | Adjust DCRC1pD driver offset so that IbIs peak (QET bias around 180) is near top of output scale. |
| 1321 | Start automated IbIs on DCRC1pD. 350 to 50 uA step -2. |
| 1425 | Make new directory in /byseries and move the QB_scan files from /livedata to the new directory. |
| 1440 | Restart DAQ programs with only DCRC3 enabled. |
| 1440 | Adjust DCRC3pA driver offset so that IbIs peak (QET bias around 160) is near top of output scale. |
| 1447 | Start automated IbIs on DCRC3pA. 350 to 50 uA step -2. |
| 1523 | Begin LHe transfer @ MB = 18.5% |
| 1535 | Make new directory in /byseries and move the QB_scan files from /livedata to the new directory. |
| | This IbIs railed high - need to redo. Maybe the SQUID lost lock. |
| 1551 | End LHe transfer @ MB = 93.7% |
