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.
