- Lab Update - Run 77
- Donot see phonon pulses after 4th 10k pumpout which was on Saturday
- After the 3rd 10K pumpout, we see a few channels on Side 1 in transition, while two of the channels were not transitioning as if they are stuck in normal mode.
- Side 1 pC has low feedback coil resistance but the reason for Side 1 pD is not known yet.

* After fourth 10K pumpout, the working channels on Side1 are not showing pulses when we did IbIs on them.
- Tried using automated IbIs using pysequencer scripts. The sequence gets stuck at the step of Transition OFF (stopping the run).
