by David and Chad after target removed from module:

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

 An electrical check made at NHC right after TM4 moving from ITE.

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.

Megger check values were low but still within operational range.

TM#2 has failed the electrical check see attached pdf for details.

Post beam electrical check on the Ta#45 target installed on TM#4. See attached PDF.

Electrical check on TM#4 with SiC#31. See attached PDF for details.

Electrical check done on TM#2 around the 25th of June 2015, this was before the coil line leak was found.

Electrical check of TM#4 post beam with target (SiC#31) on and module without target on. There is a short between the target and EE when the target is on and when the target was removed short went away. See the PDF for details.

Electrical check of TM#4 with UC#13 at the south hot cell. See PDF for details.

TM#4 with UC#13 electrical check at the conditioning station under vacuum. See attached PDF.

Electrical check of TM2 without target after that widget has installed, electrical check with the shunts on, electrical check with the dummy target installed.

TM#2 electrical check at the conditioning station. All pumps were off but the module was not vented.

Electrical check of TM#2 with ZrC #7 installed

Electrical check of TM#2 at the conditioning station under vacuum. The resistance value of the target to 60kV common is a bit lower then what it was at the south hot cell.

TM#4 with UC#13 post beam electrical check. Also and electrical check was done without the target on.

TM#4 electrical check with Ta#46 attached.

TM#4 electrical check at the conditioning station with Ta#46 target.

TM#3 electrical check at the south hot cell, no target, all value are done at 1000Volts. See the attached PDF for the results.

Electrical checks of the TM#2 with the old SiC#32 and without the target. See attached PDFs.
