Starting to repopulate HAM1 with ISC Components
Oli, Matt, Camilla
We started to repopulate HAM1 with ISC components following the locations show in D1000313-v19.
On the +X side, we placed: M14, HW1 (facing wrong direction), M17, M1, M7, M13, M10, M11, M12, BD4, BD5, BD6a, BD6b, BD7, BD17 (in different location due to masses), BD18, HiPWR BD (needs to be moved after ASC REFL beam profiling). Photos here and here.
We could still place: L2 and M15 and flip the direction of HW1 (see Corey's original photo)
We want to wait to place: M16, the periscope, Beamdiverters, LSC POP diodes, BD1, BD2, as it will make alignment or beam profiling of the diodes tricky.
On the -X side, we placed: M2, M6, L1, M18. Photo here.
We could still place: M5 (once we are happy with RM1), the majority of the beamdumps, the SLED.
We want to wait to place: the ASC and LSC diodes until some beam profiling/ beam size measurements have been done.
The 4 optics that are still in pans (L2, M15, M16, M5) have all been moved to pan 2 (lower shelf) and the periscope is on the bottom shelf.

Late entry, Jim and I worked the last few half days to lace up all of the cabling for SUS, SEI, and IO/ISC in prep for the main reinstall of table components. Fil, some Richard, and I did preliminary ground loop checks on all SUS and IO/ISC cables so we have a handle on the situation before complicating with components. I routed cables on the table top in an attempt to be near where things plug in but also not in the way of landing objects. Further dressing and coiling will be needed after troubleshooting plugins with components as we go. Pics of the pre round of cabling.

This morning we swapped the direction of HW1 so that it is facing the same as before. We also placed L2, M15, LSC POP A and ASC POP X although the diodes are not cabled up yet. They can be next week as Daniel confirmed chassis are powered off.
ASC POP X is new, the box is marked D1102004-v6 S/N 016 S1300637, ICS link. Have added this to the D1000313 BOM googledoc and HAM1 ICS assembly.
Tagging with EPO to document the process.
