Entry  Friday, June 08, 2012, 11:07, David Wang, Conditioning Station, Standard Operation, TM1, Ta38, conditioning staion and TM1 is under TP1 and TP2 pumping now. 

I connected vacuum system to TM1 and conditioning station and started two turbo pumps yesterday. The pumping an d vacuum readings  are verg good so far(all below 5xE-6 torr). Helium pressure test on heat shield circuit will be fulfilled next week.

Entry  Thursday, June 07, 2012, 11:58, Bevan Moss, Conditioning Station, Standard Operation, TM1, Ta38, Module Move from SHC to TCS 

TM1 was moved from SHC to the TCS. The mode took roughly 1 hour. During the move the north east corner of the containment box caught slightly on the flange of the vacuum vessel and then slipped off. The contact was minimal but should none the less be noted. After sliding off of the flange the module did not crash into the other sides of the vacuum vessel, this is why I believe the contact was minimal. It should be noted that the corner of concern is the one that is most difficult to see.

Entry  Wednesday, June 06, 2012, 14:33, David Wang, South Hot-Cell, Standard Operation, TM1, Ta38, leak check heat shield circuit 

Chad and I did a leak check on heat shield circuit after target is installed on TM1.The leak detector pumping down is smooth. The base leak rate is 0.0xE-9 atm.cc/sec. The base pressure is 0.0xE-4torr. Chad checked helium flow downstairs and sprayed helium to each joints for 2 seconds.The first joints is good and there is no any response on leak detector.we double checked it again and got the same result. On the second joint, Chad sprayed helium 2second. After 15 second of spraying,the leak detector got a response which climbed to 3.2xE-8 atm.cc/sec max,and back to 2.5 XE-8 atm.cc/sec. Chad tried to tighten the fitting. During his tight, the leak rate response to 7.5x E-8 atm.cc/sec momentarily. After the tightening ,the leak rate back to 0.0x E-9atm.cc/sec whic is the base.So we sprayed the helium to the joint again.This time ,there is no any response on leak detector. We checked this joint  again and got the same result which is no response. Finally, Chad flush the helium around the target for 10 second ,and during 45 sec observation time there is no any response on leak detector. I would say the heat shield circuit is leak tight so far. I will do a helium pressure test on it once the TM1 is moved the CS.

Entry  Wednesday, June 06, 2012, 13:36, chad fisher, South Hot-Cell, Standard Operation, TM1, Ta#38, Target Change Nb#6 - Ta#38 

Nb#6 was removed from TM1...it looked very clean.

Ta#38 was installed onto TM1...fit well.

Isaac Earle did this change with supervision in an effort to cross train.

TM1 containment box was checked for damage from the "bump" it got during yesterday's move. There was new scratches on the shutter side panel. Picture to follow.

The front containment box panel was "difficult" to remove...it required a good pull to get off.

 

Entry  Wednesday, June 06, 2012, 08:21, David Wang, ITW, Standard Operation, TM1, , TM1 disconnected in ITW 

I disconnected TM1 in ITW yesterday morning.The general radioactive level in ITW over the TM top (300mm) is about 350 usv/hr. contacting level on TP1 and TP2 are 1.0-1.2 msv/hr. I took 0.22 msv dose .The module is moved to

south hot cell later and a shielding plug is put back to ITW. Everything is fine.

Entry  Tuesday, June 05, 2012, 15:06, Bevan Moss, ITW, Standard Operation, TM1, Nb#6, Module move from ITW to SHC 

 TM1 has been moved from ITW to the SHC. The move did encounter some issues, one of the railings for preventing people from falling into the MAA was hit with the containment box. This caused the module to rotate. The module rotated ~90 degrees before the problem was noticed. The module was backed off from the post once noticed but had already freely rotated. The box was inspected with the cameras prior to being inserted into the SHC. No damage was detected. The error came as a result of over confidence. It did appear it was going to be hit but as the module moved closer I believed that there would be clearance. The angle of the camera has caused the module to appear it was going to hit thing before in the past but it actually (once the module was closer to the object) had several feet of clearance. This is not a mistake I will make again.

Chad Fisher, Grant Minor, and Don Jackson, have been alerted about this. Chad will complete another visual inspection in the hot cell. David will take swipes of the pole to ensure there is no contamination. 

Entry  Tuesday, June 05, 2012, 12:20, Bevan Moss, South Hot-Cell, Standard Operation, TM1, Ta#38, Target inserted into HC 

Ta#38 has been placed into the south hot cell. Swipes of the tool port were taken there was a count of 600 on the floor and 150 on the walls and top. 

Entry  Monday, May 28, 2012, 13:05, David Wang, ITE, Standard Operation, , , I moved 5 shielding blocks from ITW to ITE . 

5 shielding blocks have  been transferred from  ITW to ITE. ITE ventilation is opened, and ITW closed. All ITE water  signals have been checked for frequency and strength.They are all good. ITE is ready for taking proton beam.

Five targets were moved to the mini storage today in preparation for transfer of the targets to the F308s later next week. The moves went well. See the attached files for the vault and mini storage details.

Entry  Tuesday, May 22, 2012, 15:19, David Wang, ITE, Standard Operation, TM4, sic 27, TM4 in ITE under pumping 

  I started 6 turbo pumps this afternoon. The TM4 and ITE are under pumping now. The vacuum is fine so far. We will see a better picture tomorrow morning. In order to keep the system pressure at 90 psi, I just turned on all the water to TM4 circuits. The water interlock check which related to TM4 water circuits is all done. I will do the rest part (XTpage related to 2A beam) next week once I turn on all the water to ITE. The ITE and TM4 will be ready for HV conditioning once the vacuum is ok.

All TM4 connections in ITE is done. The station and TM4 is under roughing now.

Entry  Tuesday, May 22, 2012, 10:50, Travis Cave, ITE, Standard Operation, TM4, SiC#27, module moved 

Module has been moved from conditioning station to the east target station. Move went well.

Entry  Tuesday, May 22, 2012, 10:00, David Wang, Conditioning Station, Standard Operation, TM4, sic 27, helium pressure test on heat shield circuit 

I did a helium pressure test on heat shield circuit. The leak detector is concected to the TM4 primary vacuum system.The IG1 is 1.1xe-6 torr,PNG4 is 1.5 x E-6torr,and IG4 is 2.1 XE-6torr.leak detector base leak rate:0.0xE-9 atm.cc/sec, base pressure is 0.0x E-4 torr.Applied 80psi helium to heat shield circuit for 4 mins .There is no any response on leak detector during 4mins time. There is no pressure change during the test time. The heat shield circuit is leak tight.

Electrical check of TM#4 with SiC#27 under vacuum at that conditioning station. See attached PDF for details.

Entry  Friday, May 18, 2012, 08:37, David Wang, South Hot-Cell, Standard Operation, TM4, sic 27, leak check on heat shield circuit 

Chad and I leak checked the heat shield circuit after sic 27 target  installed. It took 20minutes  to pump down the circuit to the leak detector bottom scales. The leak detector is calibrated today,and all the vacuum lines and connections are leak checked by spraying helium. Chad sprayed helium to each vc fittings for 2 seconds. There is no any response on leak detector . The test repeated one time and the result is same. Chad flushed  helium around the target for 10 second .This time leak detector also have no respone.  The heat shield circuit is leak  tight at this stage . We will move TM4 to conditioning station and pressure helium test the circuit.
