| Status | Run 76 in progress |
|---|---|
| Setup | Cable 2/1/3 → diverter/nothing/nothing → DCRC50(3)/DCRC55(1)/DCRCX(4) |
| 1450 | MC/Coldplate = 28.6/140 mK, Still = 1.12 K / 0.120 mbar / 0 mW, G1/G2= 176/177 mbar, 1K Pot = 18° / 1.64 K / 24±2 mbar. MB = 28.9% |
| 1450 | Goldman = 72.7 mK @ 632 uB excitation |
| 1606 | Begin LHe transfer @ MB = 27.0% |
| 1644 | End LHe transfer @ MB = 95.3% |
| 1705 | Fill LN2 cold trap bath |
| 1715 | Solder a LEMO cable to a Dsub50 diverter board, DCRC-side (male connector), with center conductor on Pin 42 and shield soldered to Dsub shell/ground. Pin 42 is LED1. The intent is to use this to feed a TTL signal into a DCRC, and set the DCRC to connect LED output to pA - then we can trigger on the external TTL signal. Something like this was done back in Run 62. |
