After another marathon day in chambers, Fil, Richard, Travis, and I finally finished connecting the newly fabricated ITM ESD feedthru connections in-chamber and their subsequent testing (FRS Ticket 5033).  The testing, of course, was not straight forward and we walked around troubleshoot a few things here and there.  We struggled with the ITMX BIAS intermittently failing the HIPOT testing and continuity checks (see issues with this reported last year 27562).  We tracked down the issue to the pin at the other end of the cable we reterminated (and have not touched during this vent) which led to me disassembling the connector a bit and looking for shorting mechanisms.  I didn't find any, but upon reassembling the connector, things seemed to test fine.  Sigh.

Fil will likely post the full numbers above or below this alog for both ITMX and ITMY testing (which included HIPOT).

Meanwhile, the ground checks of the SUS cables that were checked on ITMX, ITMY, and the BS which failed a few days ago were fixed via a variety of reseating the connection fasteners at the feedthru end of the cable, remedying pinch points of cables in-vacuum, or resolving to have EE fix it somewhere on the outside.  Most of the cables had not been touched during this vent, with the exception of the ITMX PUM one which had migrated out of it's viton pad seat during the ITMX rebuild last month.

So, really, really we could do the BSC 1, 2, 3 closeout tomorrow.
