Entry  Friday, April 08, 2016, 08:48, David Wang, ITW, Standard Operation, , , ITW water signal interlock check. 

I did a ITW water signals interlock check with ISAC opp. They are checked once a year before first beam on.

2016-04-13 Same test is done on ITE also. Everything is good.

Entry  Monday, April 11, 2016, 09:42, David Wang, Conditioning Station, Standard Operation, TM4, , Helium pressure test on TM4 HS line at CS with new Lp Ta target 

70 psi helium , 2 minutes. Base leak rate 0.0x E-9 atm.cc/sec. base pressure 0.0XE-4 torr. no response on LD.The line is good.

Entry  Monday, April 11, 2016, 13:44, David Wang, Conditioning Station, Standard Operation, TM4, , I stopped TCS and TM4 vacuum pumps. 

The TM4 is still under vacuum at TCS. It will be vented tomorrow morning.

I disconnected TM4 vacuum system at TCS.

Entry  Tuesday, April 12, 2016, 11:41, David Wang, ITE, Standard Operation, TM4, , TM4 has been connected in ITE. 

Tm4 has been connected in ITE. The ITE and TM4 is under roughing now. ITE

Turbo-pumps have been started. Everything is fine.

Entry  Wednesday, April 13, 2016, 10:46, David Wang, Conditioning Station, Standard Operation, TM2, , TM2 and TCS vacuum system has been connected.  

TCS is under roughing now.

2016-04-14, Started TCS and TM2 turbo-pumps yesterday afternoon. Overnight pumping down is fine.

Entry  Thursday, April 14, 2016, 12:56, David Wang, ITW, Standard Operation, TM1, , 5 shielding blocks have been moved to ITW. 

The ITW is configured to take proton beam.

Entry  Monday, April 18, 2016, 09:07, David Wang, Conditioning Station, Repair, TM2, , venting TCS with argon. 

Anders reported a possible air leak on TM2 and TCS by watching RGA  this morning. I found the quick connector on F terminal on the top of the module is leaking air. It is only used as "X" terminal for Febiad without  water. So, it should be blind capped instead of installing a quick connector. It was installed with a  blind cap before. I borrowed it for leak check on coil lines at SHC, but forgot to put it back right away. Instead, I put a quick connector on it later. This caused the problem. Anyway The TCS need to be vented , and a blind cap  will be installed on the F terminal.

2014-04-18, 9:24AM, I changed the quick connector with a blind cap on F terminal. the rough pump is started now.

Entry  Tuesday, April 26, 2016, 10:47, David Wang, Conditioning Station, Repair, TM2, , TM2 leak check at TCS, water test. 

The following water circuits in TM2 are connected at TCS and running with water now : target oven+ - ( one circuit), tube heater+ -( one circuit), coil1 and 2(one circuit), MSP, and EE. The HS and window are open circuits now so they can not be supplied with water.  During the check before we knew HS and window circuit were close to perfectly sealed. So, The test result should not be affected without them

The TCS water pumps are started at 8:28 AM. All TCS high vacuum gauge readings are getting slight better after that.

Entry  Thursday, April 28, 2016, 06:28, David Wang, Conditioning Station, Maintenance, TM2, , TCS water system are turned off. 

 TCS water system worked fine overnight. I turned off TCS water system at 6:16 AM this morning. Start of purging TM2 water lines for helium pressure test again this morning.

2016-4-28 7:58AM. Disconnected TM2 water lines at TCS. Purged them with compression air each for 5 minutes. 

Entry  Friday, April 29, 2016, 08:01, David Wang, Conditioning Station, Maintenance, TM2, , TM2 leak check at TCS, helium pressure test 

Anders and I finished the most part of TM2 water lines helium pressure test yesterday.I list the system parameters and test result as below:

TCS  IG1: 9.8XE-8 torr,  TCS IG2: 9.6Xe-7 torr, TCS IG1S: 3.5XE-9 torr, TCS CG1A: 10 m torr

Helium pressure: 70 psi. Test time: 5 minutes for each individual circuit.  1 hour for all  lines together test.

 Leak detector base leak rate:0.0 X E -9 atm.cc/sec, base pressure 0.0X E-4 torr. LD was always restored or closely restored to the bottom  scale after each individual test.

 

Circuit Result (atm.cc/sec)
EE 0.0X E-9
Target Oven + 0.0X E-9
Coil 1   P-Q 0.0X E-9
Target Oven - 1.0X E-9
Tube Heater- 4.1X E-9
Tube heater+ 1.6X E-8
Coil 2    R-U 6.6X E-9
MSP 1.4X E-7
All above together (1 hour) 2.3X E-7
HS Open circuit . No test
Window Open circuit.  No test.
GE  7.2X E-7

The HS and Window lines will be tested later with new target installed and  window line gaskets restored.

Entry  Friday, April 29, 2016, 10:06, David Wang, Conditioning Station, Standard Operation, TM2, , I switched off TCS and TM2 vacuum pumps. 

  I switched off TCS and TM2 vacuum pumps. The TM2 will be disconnected at TCS today and moved to silo on next Monday.

Entry  Monday, May 09, 2016, 08:43, David Wang, Conditioning Station, Repair, TM3, , I reinstalled all the side panel on TM3 service cap. 

They were moved for TM3 inspection job last week. All the bolts on the panel are hand tight only now since they will be removed out for camera installation during next stage inspection.

Entry  Tuesday, May 10, 2016, 13:54, David Wang, South Hot-Cell, Standard Operation, TM2, , SHC, TM2 leak check on window line and HS line. 

Chad and I leak checked the TM2 HS and window lines after new target installation.  The window line was very easy pumped down on LD. But, The HS line only could pumped to 2-3 torr at first. Chad changed the VCR gaskets on HS line(target). It solved the problem. The LD could pumped  both of Window and HS lines to the bottom scale. Chad sprayed lots helium around the VCR joints.  No leak has been found. WE will do helium pressurizing test on them at TCS.

Entry  Wednesday, May 11, 2016, 13:15, David Wang, Conditioning Station, Maintenance, TM2, , TCS tank top flange seal is changed this morning 

I changed TCS tank top flange seal(o-ring 42.00"ID X 0.275" DIA) this morning before TM2 was moved to TCS.

Entry  Wednesday, May 11, 2016, 13:16, David Wang, Conditioning Station, Standard Operation, TM2, , TM2 and TCS vacuum system has been connected. 

TM2 and TCS vacuum system has been connected. I started all turbo pumps. Everything is good so far.
