- 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 = 10.05 mm |
| 1450 | Goldman/Tower/MC(H35)/Coldplate = 49.1/92.8/38.5/210 mK, Still = 1.617±0.002 K / 0.130 mbar / 0 mW, G1/G2= 254/228 mbar, 1K Pot = 1.62 K / 18±1 mbar, MB = 26.1%. |
| Still thermometer is reading much more stably today. (Possibly because I put the bridge onto Autorange - it had been off lately.) | |
| 1502 | Begin LHe transfer @ MB = 26.0% |
| 1540 | Fill LN2 cold trap bath |
| 1540 | End LHe transfer @ MB = 90.7% |
