Entry  Wednesday, September 26, 2018, 07:14, David Wang, Conditioning Station, Repair, TM3, , TM3 HV test at TCS. 
I did a HV test on TM3 at TCS yesterday. HV Ramp up speed: 1KV per 5 minutes when below 30KV,1KV per 10 minutes from 30-36KV. There is no major spark
below36 KV .  I could see  lots small and big vacuum response on IG1 and PNG2 when conditioning from 30-36 KV, especially when closing to 36
KV.  However, At 36.4 KV, There is a big continuous spark occurred. It could not be stopped until I lowed the HV to 14KV. I have to ramp up from 14

The west exit #2 module has been moved from the south hot cell to the conditioning station.
Entry  Monday, October 29, 2018, 10:43, David Wang, Conditioning Station, Repair, , , ITW exit 2 leak check at TCS. 
I did a leak check this morning on exit 2 module at TCS. LD base  leak rate is 4.00XE-9atm.cc/sec, Base pressure is 0.00 X E-4 torr. All seals,
bellows, and flanges are checked. The new FC5 bellow is good. There is a big leak up to 2X E-6 atm.c/sec has been found on IG1S side panel . The panel
itself  will be replaced this time. Machine shop is working on it.. Two small leaks in E-9  atm.cc/sec range have been found on the  o-ring

TM#2 with UC#25 has been moved from the south hot cell to the conditioning station.
Entry  Thursday, November 01, 2018, 11:42, David Wang, Conditioning Station, Standard Operation, TM2, UCx 25., TM2 HS line helium pressure test at TCS and helium spray at SHC.. 
Chad and I did  leak check on TM2 HS line at SHC yesterday. Base LR 0.0XE-9 atm.cc/sec.   No response on LD. during helium spray.  
Today , I did helium pressure test at TCS. base LR 0.0xe-9atm.cc/sec. applied 70psi helium for 3 minute. leak rate slowly climbed to2.2 Xe-7 atm.cc/sec
ate stopped there.  The result is close to before.
Entry  Monday, November 05, 2018, 14:27, Anders Mjos, Conditioning Station, Standard Operation, TM2, UC#25, Target module disconnected 
Frank and Anders disconnected the water and electrical connections this afternoon after the target was conditioned over the weekend. The heater ramping
program ran with the wrong gauge selected, causing the vacuum to go higher than planned. The module will be moved to ITW tomorrow.
