Terminated both the downstairs and upstairs ends of the cables.

Body: 

Discussed with task owner. Parts not quite here yet, but on the way. Plenty of other higher priority work to do by MSSG before this task.

This task will be opportunistically progressed as time and personnel are available. At this time, with our current understanding of the East Arc magnet overheating issue, there are no succeeding tasks dependent on this one. That could change, which could elevate this task from nice-to-do/opportunistic to must-do ASAP. MWP-11776 on-issue.

Note: this is for the quad stack LCW manifolds in the east arc.

Ali, here is some SCL data from Feb/Mar 2025 using the C laser at 14500/19000. The laser size and position matter so useful to group or at least keep track of these parameters. If you want to confirm which photocathode is used search POLOG on/before Feb/Mar. Note, there isn't too much here to look at, not much charge extracted. MOLLER will run at 65uA, e.g. can extract e.g. dQE/dP or dI/dP and from this high QE data and ask what happens when the dP modulation is 1%.

Michele, any idea how to access SCL data collected prior to 2024, maybe I'm looking in the wrong place?
