HAM1 feedthroughs

(Alexa, Daniel)

We checked the vacuum feedthrough flanges on HAM 1 and noticed that none of the double 5-way coax flanges were installed. The missing positions are D1-3, D4-2, D5-2, D6-2 and D6-3 (see D1002872). We are also missing a double D-sub feedthrough flange on position D1-3. With some help we were able to locate the missing flanges and they are awaiting installation.

We noticed that purge air port is located on D5-3 rather than D4-3 as the drawing would indicate. The easiest way to accommodate this difference is to simply route the TT signals through D4-3. It is already equipped with a double D-sub feedthrough flange.

We were able to find some of the in-air cables. The beam diverter cables were routed to the wrong side of the chamber. They were too short to reach the designated flange, so we had to reroute them. We are missing the cables for the LSC PD DC signals and still have to install the coax cables. We have cables for the picomotors, but will do a test first.

There is no SUS satellite amp in the ISC-R4 rack. All units are at LLO and are being shipped.

The picomotor cable has been tested and hooked up. We also installed the one that goes to ISCT1.

The beam diverter cables were tested and installed on D1-1 and not at D2-1 as shown in the drawing. D2-1 is inaccessible.
