- Lab in-personnel: Matt
| Status | Run 75 in progress |
|---|---|
| Setup | Tower Faces 5/3/2 → Cables 2/1/3 → nothing/diverter_board/nothing → DCRC55(1)/DCRC50(3)/DCRCx(4) Lead shield in place. Am Source y = 20.01 mm |
| 1020 | Goldman = 41.2 mK. Drifting down slowly overnight from 41.4 mK. |
| Let's do another set of automated IbIs at this much lower temperature | |
| 1035 | Disable DCRC3&4 on ODB. We're only taking data with one DCRC for IbIs. |
| 1040 | Adjust DCRC1pA driver offset so that IbIs peak (QET bias around 290) is near top of output scale (around 1V). |
| oops, had the logger on, so some junk data was saved | |
| 1055 | Start automated IbIs on DCRC1pA. 550 to 250 uA step -2. |
| 1055 | Goldman = 41.2 mK |
| 1130 | Make new directory in /byseries and move the QB_scan files from /livedata to the new directory. |
| 1135 | Adjust DCRC1pB driver offset so that IbIs peak (QET bias around 320) is near top of output scale (around 1V). |
| 1139 | Start automated IbIs on DCRC1pB. 500 to 200 uA step -2. |
| 1140 | Goldman = 41.2 mK |
| 1210 | Make new directory in /byseries and move the QB_scan files from /livedata to the new directory. |
| 1220 | Adjust DCRC1pC driver offset so that IbIs peak (QET bias around 330) is near top of output scale (around 1V). |
| 1220 | Start automated IbIs on DCRC1pC. 500 to 200 uA step -2. |
| 1220 | Goldman = 41.3 mK |
| 1300 | Make new directory in /byseries and move the QB_scan files from /livedata to the new directory. |
| 1305 | Adjust DCRC1pD driver offset so that IbIs peak (QET bias around 210) is near top of output scale (around 1V). |
| 1308 | Start automated IbIs on DCRC1pD. 400 to 100 uA step -2. |
| 1310 | Goldman = 41.5 mK |
| 1500 | Make new directory in /byseries and move the QB_scan files from /livedata to the new directory. |
| The range chosen for DCRC1pA auto IbIs was too high, need to redo it | |
| 1525 | Adjust DCRC1pA driver offset so that IbIs peak (QET bias around 290) is near top of output scale (around 1V). |
| 1531 | Start automated IbIs on DCRC1pA. 500 to 200 uA step -2. |
| 1535 | Goldman = 41.5 mK |
| 1715 | Make new directory in /byseries and move the QB_scan files from /livedata to the new directory. |
| 1700 | Goldman/Tower/MC(H35)/Coldplate = 41.7/77.8/33.3/172 mK, Still = 1.30 K / 0.110 mbar / 0 mW, G1/G2= 248/211 mbar, 1K Pot = 1.61 K / 17±1 mbar, MB = 25.6%. |
| 1710 | Begin LHe transfer @ MB = 25.4% |
| 1715 | Fill LN2 cold trap bath |
| 1741 | End LHe transfer @ MB = 91.8% |
| 2130 | Restart DAQ programs with only DCRC3 enabled |
| 2135 | Adjust DCRC3pA driver offset so that IbIs peak (QET bias around 190) is near top of output scale (around 1V). |
| 2142 | Start automated IbIs on DCRC3pA. 400 to 100 uA step -2. |
| 2145 | Goldman = 41.9 mK |
| 2215 | Make new directory in /byseries and move the QB_scan files from /livedata to the new directory. |
| 2220 | Adjust DCRC3pB driver offset so that IbIs peak (QET bias around 180) is near top of output scale (around 1V). |
| 2225 | Start automated IbIs on DCRC3pB. 400 to 100 uA step -2. |
| 2225 | Goldman = 41.8 mK |
| 2300 | Make new directory in /byseries and move the QB_scan files from /livedata to the new directory. |
