2026-06-29 H1ISIH23 HAM3 ISIK Transceiver Cabling Re-dressed
J. Kissel

This morning, I re-installed the H1SPIH23 pathfinder's photodiode and picomotor cable-table-brackets (CTBs) that had been temporarily moved to upgrade the Corner 1 H1 capacitive position sensor (see LHO:90791), and re-dressed the cabling cable clamps.

As mentioned in passing in LHO:90750 the CRS team will now consume the "spare" SPI_HAM3_004 quadrupus leg, that's J2 of the S2500513 instantiation of D2400342, which manifests as CH8 on the TCSY_C02, Controller 10, PICO G picomotor controller driven by the Corner 2 ECAT chassis -- which shows up on the H1SYSCSAUX computer's SDF system. So this has been routed in the +X direction and up in +Z to the table top on the +Y corner.

I'll post pictures of all the re-dressing in the comments so I can better caption them.

Zoom of how the 2x D25 cables are routed with a nice soft s-curve as the cables jump from the ST1 suspended stage to ST0 support stage.
