Entry  Tuesday, June 07, 2016, 11:37, David Wang, ITE, Standard Operation, TM4, Ta#47, TM4 has been moved from ITE to SHC 

Bill and Yasmine did the move. Everything is good.

Entry  Tuesday, June 07, 2016, 11:36, David Wang, ITE, Standard Operation, TM4, Ta#47, TM4 has been disconnected in ITE. 

Dan and I disconnected TM4 in ITE. HS water lines has been purged.

Entry  Thursday, June 02, 2016, 11:59, David Wang, South Hot-Cell, Repair, TM3, , 5K mega test on TM3 5K_mega_check_on_TM3.pdf

I did a 5KV mega test on TM3.  Only5Mohm @5kV between coli line PQ and chassis(ground). It confirmed the close gap between P,Q and GE. Other lines are ok. See attachment.

See attachment for sparking signs of the water lines mentioned  above (Coil and Ground Electrode lines) in TM3 Source Tray.

PLEASE NOTE: the resistance values for A and B on David's attachment are not correct since these measurements were done after Chad removed the target and the heat-shield bracket was moved, so consequently the water lines were not at their nominal locations. Once they were back in plac,e David took another measurement and the resistance values for A and B showed also 3,000 MOhm (as it was for most of the lines). The only lines that still showed a low resistance were the Coil lines. 

Entry  Friday, June 03, 2016, 11:35, Travis Cave, South Hot-Cell, Standard Operation, TM3, no target, module moved 

TM#3 has been moved back to the north east silo.

Electrical check of TM#3 no target at the south hot cell. see attached for results.

Entry  Tuesday, May 31, 2016, 09:45, Travis Cave, South Hot-Cell, Standard Operation, TM3, no target, module moved 

TM#3 has been moved from the NE Silo to the south hot cell.

Entry  Wednesday, May 25, 2016, 14:08, David Wang, ITW, Standard Operation, TM2, Ta#48, TM2 has been connected in ITW 

TM2 has been connected in ITW by Dan.M and David.W. All turbo-pumps have been started. Everything is good so fine.

Entry  Wednesday, May 25, 2016, 10:57, Travis Cave, ITW, Standard Operation, TM2, Ta#48, module moved 

TM#2 with Ta#48 has been moved from conditioning station to the west target station.

Entry  Tuesday, May 24, 2016, 10:52, Travis Cave, Spent Target Vault, Standard Operation, , UC#15, Spent Target move Vault_Storage_May_24_2016.pdf

Spent UC#15 has been moved from the south hot cell to the spent target storage. It was placed in pail number 136, and placed in spot C of tray one. It was 14.1mSv/hr upon removal from the south hot cell.

Entry  Tuesday, May 24, 2016, 10:42, David Wang, Conditioning Station, Standard Operation, TM2, , Target Hall schedule for beam schedule 130 (Apr- Sep) Target_Hall_shedule_130_Apr_to_Sep_2016.xlsxTarget_Hall_shedule_130_Apr_to_Sep.mppTarget_Hall_shedule_130_Apr_to_Sep.pdf

Weekly update the TH schedules. See attachments 1, 2,3.

Entry  Tuesday, May 24, 2016, 10:39, David Wang, Conditioning Station, Standard Operation, TM2, Ta#48, TM2 and TCS turbo-pumps have been switched off this morning. 

The TCS and TM2 are still under vacuum without venting

Entry  Friday, May 20, 2016, 10:38, David Wang, Conditioning Station, Standard Operation, TM2, Ta#48, Helium pressure test on TM2 with new Lp Ta target 

LD base LR: 0.0 X E-9. Base pressure:0.0 X E-4. 70 psi helium. 5 minutes each circuit.

window 0.0X E-9  
HS 0.0X E-9  
EE 0.0X E-9  
Ta+ 0.0X E-9  
Ta- 0.0X E-9  
coil1 R-U 0.0X E-9  
Coil2 P-Q 5.0X E-9  
Tube- 5.1X E-9  
Tube+ 1.1X E-8  
MSP 3.5X E-9  

The bigger leak found on MSP before was gone. Leak rate are smaller on all circuits  comparing to before. 

The leak rate on 1 hour total lines test at 70 psi is better also which is 6.6 XE-8 atm.cc/sec this time. 

Entry  Friday, May 20, 2016, 08:13, David Wang, Conditioning Station, Standard Operation, TM2, Ta#48, I switched off TCS and TM2 water system 

Disconnected  TM2 at TCS(vacuum system still on). Purged all TM2 water lines for helium pressure test.

Entry  Tuesday, May 17, 2016, 14:15, Travis Cave, ITW, Standard Operation, TM1, UC#15, module moved 

TM#1 with UC#15 was moved back to the west station due to alpha concerns.
