- Lab Update - Run 77
- Second 10k pumpout. Cool to base yesterday at 6 pm.
- In last pumpout, not all DCRCs were showing traces. Figured out to do zap SQUIDs using pysequencer.
- After zapping, all channels were live in DCRC3.
- Checked all DCRCs. DCRC3 was not responding like last time. After multiple power cycles, DCRC3 show traces on all channels. Started mini-IbIs on DCRCs last night.
- SQUIDS status:
| DCRC1 PA/PB/PC/PD = (SQUID is not showing modulation)Side2pC/Side2pF(not transitioning)/(not transitioning)Side1pC/(not transitioning)Side1pF | |
| DCRC3 PA/PB/PC/PD = Side1pE /Side1pB /Side1pD/ Side2pE(not transitioning) | |
| DCRC4 PA/PB/PC/PD = (SQUID is not showing modulation)Side2pB/ (SQUID is not showing modulation)Side2pA/ Side1pA/ Side2pD |
- QET bias:
| DCRC channel | Detector channel | QET bias @ dP/dI = - uV | Previous Run |

| DCRC1pC | Side1pC | ||
| DCRC1pD | Side1pF | 154 | 274 |
| DCRC3pA | Side1pE | 140 | 246 |
| DCRC3pB | Side1pB | 210 | 224 |
