Don Jackson and Myself completed started an electrical test on TM2. All lines passed the with OL to ground. When testing in between the lines individually there were several lines that read other than OL. It was decided to abandon the testing as there were too many "failures". The results are attached. The testing will be repeated in the conditioning station with vacuum. It is not expected that this will change anything as during a quick visual inspection it appears the lines are touching. Of note the water block jig was removed this morning by Chad.

 The four electrical check done on TM#2 during the source tray change.

The bundle of electrical checks, first one is the Iglis that failed, the second is the everything passed at the hot cell and the third is a the conditioning station under vacuum.

Results of the electrical check of TM#2 with no target after the repair and with the SiC#35 mounted on the module.

Megger checks were exceptionally high (good).  Readings taken less than 2 hours after reading low values from end of run on Nb#6.  Tests on Ta38 will be repeated at conditioning station later.

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.

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.
