Entry  Saturday, December 03, 2016, 10:01, David Wang, ITW, Repair, TM2, , venting ITW and TM2 with argon. 
A short between TM2 EE and bias is produced yesterday during tube heater ramp up.  Alex asked for an argon venting on ITW to see if the problem
could be solved by venting and pumping down yesterday.  I set up argon venting system in electrical room and started the venting at 8:30 AM this morning. 
It will take 5 hours to vent the ITW to 760 torr(mechanical gauge reading).  The venting system pressure is set as 2 torr. A pressure relieve valve
Entry  Monday, December 05, 2016, 10:10, David Wang, ITW, Standard Operation, TM2, , Five shielding blocks have been transferred from ITE to ITW.  
The ITW is configured to take proton beam.
Entry  Thursday, January 12, 2017, 14:24, David Wang, ITW, Standard Operation, TM2, , ITW primary and secondary vacuum vessel winter shut down leak check. 
TM2 is located in ITW for this leak check. Leak detector is installed between ITW BV2s as before. LD base leak rate 0.0XE-9atm.cc/sec, base pressure
0.0XE-4 Torr. First , I leak checked dump module top flange seal which a small leak was found in last year winter shut down. This time,all ITW  turbo-pumps
cooling fans are switched off during the check. Lots helium are sprayed around the dump module top flange this time. I did not see any response on LD. 
Entry  Monday, January 16, 2017, 09:32, David Wang, ITW, Standard Operation, TM2, , Helium pressure test on TM2 water llines at ITW 
TM2 helium pressure test result at ITW. 70 psi helium 3 minutes on each circuit. LD base LR0.0XE-9atm.cc/sec  BP 0.0XE-4torr.  ITW IG1 1.22Xe-7
torr, ITW IG1S 1.31XE-7torr, ITW PNG4 2.66XE-6Torr(ITW TP4 off).
 
Entry  Tuesday, January 24, 2017, 15:24, David Wang, Conditioning Station, Standard Operation, TM2, , TM2 electrical check and leack check. 
I did electrical check before and after Fefiad target installation on TM2. The RU (coil) Is till short to 60KV as before. Other result are good. After
Febiad target is installed, Tm2 HS line is leak checked. On leak detector, base leak rate pumping down is much slow  than before.  The base pressure
still could be pumped down to 0.0XE-4 torr.  After a long time wait, Chad and I leak checked at 2.2XE-8 atm.cc/sec base leak rate. Chad sprayed lots
Entry  Tuesday, January 24, 2017, 15:29, David Wang, Conditioning Station, Standard Operation, TM2, , TM2 has been moved to TCS . 
I connected TCS vacuum system to TM2. The station is under roughing now. All turbo pumps will be started soon.
Entry  Tuesday, January 24, 2017, 15:32, David Wang, ITW, Standard Operation, TM2, , TM2 was moved from ITW to SHC this morning. 
The move is smooth. Yasmine and Travis did the move.
Entry  Friday, January 27, 2017, 08:44, chad fisher, South Hot-Cell, Standard Operation, TM2, Ta#50, UCx #18 - Ta Feibiad Dummy installed. Target Change Waterline interference TM2_Waterline_interference.jpg
On Tuesday, January 24th UCx#18 was removed from TM2 and Ta febiad dummy installed. I encountered the same issue mounting the new target as last time.
Was able to determine that the issue is the routing of the waterlines to the right-hand (as viewed from the operator) high current tube heater. The lines
interfer the the target mounting plate (bottom right hand corner).
Entry  Friday, January 27, 2017, 10:52, David Wang, Conditioning Station, Standard Operation, TM2, , TM2 has been moved from TCS to ITE 
The move is successful.
Entry  Wednesday, February 01, 2017, 12:23, David Wang, ITE, Standard Operation, TM2, , TM2 has been connected in ITE. 
TM2 has been connected in ITE. The SST window water lines in ITE can not be connected properly to TM2. The water line connector on TM2 window is 90 degree
CCW installed in direction comparing to TM4.This caused the problem. Solution: Two piece of flexible lines and extra male QC adapters have been used to
fix this issue.  HV cover and HV fence in ITE work  with TM2. Other connections are good as well.
Entry  Wednesday, March 08, 2017, 14:09, David Wang, ITE, Maintenance, TM2, , ITE IG1S increasing. ITE_IGIS_surge.pngITE_IG1S_and_PNG4.pngITE_IG1S_back_to_normal_overnight.pngITE_IG1S_behavior_from_Feb_08th_to_Mar_10th.png
By retrieving data further, It has been found no directly relationship between IG1S surging and dump plug water opening. Vacuum surging is 10minutes
ahead dump water supply to circuit. SEE attachment 1. Also, The ITE IG1S start to behavior unusual in middle of Feburary. See attachment 2. Today, 
ITE IG1S is still slowly climbing up. I decide to leak check ITE vacuum vessel. Before  leak check, for more information and trouble shooting. I closed
