RU( coil 1), F (anode), and 60kv bias(HS, Gasline, and MSP)  are shorted together. Other lines are good.  They are measured between  individual line each other  @500V. The megga showed OL. All of  them to ground are OL @500V as well. EL is grounded during check.

The electrical check of TM#2 with SiC#36 attached. Post beam at the south hot cell. See attached results allow the before beam electrical check results are posted here as well.

by David and Chad after target removed from module:

Anode to target @500V - 65Kohm
Anode to HS - dead short
Target to HS@500V -62Kohm.

Results of an electrical check on TM#1 with no target attached to it.

 I use this e-log entry for TM1 notes as well  1. TM1 IG1 is a dual filament gauge . Its filament is very close to grid now. It shorted one time during the pumping down. It still works fine so far . But, we may need to change it if we use this module in TS again.

TCS 1G1 and 1G1S are pumped to 5Xe-6 torr. IG2 stayed at 2.5XE-5 torr. Since no target is installed on module , I capped top of HS water line. Maybe, the small o-ring seal in cap is too old, I found a big leak on this seal when i use LD check it. That is the reason IG2 stayed too high. Still, Leak check and helium presuure test are fulfilled on TM1. Leak detector BLR 5XE-7 atm.cc/sec, BP 0.0XE-4 torr9.  Back up pressure is 51 mtorr which is high because of leak on HS line cap seal so LD BLR is high. At this level, Ta+-, Tube +-, MSP,  EE are good.  Other air to vacuum seal are good as well at this leak rate.  I will check and change small o-ring seal in HS cap. The TM1 is functional basically.
