- Lab Update - Run 77
- Started warming up last Friday with help from Matt, since wiki was down until the weekend. Fridge(Cernox) is at 296 K now.
- Started pumping out cryostat vacuum jacket and IVC. Will do a leak check today before dropping the Main Bath.
- Initial Plan is to swap the SQUETS (ZC 74, ZC 31, ZC 26) to that of Run 76 (ZC 70, ZC 39 and ZC 13).
| Cable2 SQUID_A reads open. Cable 2 → Stripline 41 → ZC 70 | |
| Cable1 SQUID_C and SQUID_D read open. Cable 1 → Stripline 48 → ZC 39 | |
| Cable3 SQUID_C and Feedback_C read open. Cable 3 → Stripline 43 → ZC 13 |
- Recall that in Run 76, we had 4 phonon channels which can't be unrailed and during warmup, the following was found
- All the 4 phonon channels (pA, pC, pE, pF) are on Side 1 with the current channel map.
- We will be lowering the Tower as well to inspect whether the source mover has moved to the parking spot.
- Since we still see spikes in Fridge temperature, we will also open up the fridge further until the middle part of the IVC, to tighten bolts on the mixing chamber can.
