5 shielding blocks are transferred from ITW to ITE, Target Area is secured again after moving.

 Shielding blocks have been moved from ITE to ITW and MAA is secured.

 5 Shielding Blocks have been transferred from ITW to ITE. MAA is secured after moving.

 Five shielding blocks are moved from ITE to storage area ( one of them is sitting on B2 as limit of room) for target stations maintenance in 2025 winter shut down .

 The turbo pump, roughing pump, have been turned off and the valves for venting opened. The cooling package has also been turned off.

 TM4 IG1 filament was broken during last run  at ITE.  The broken filament is replaced with a new one today when TM4 is located at CS.

2015-06-03 , Leak checked the new 25 conflat gasket today. No leak. See attachments

TM3 service tray cover plate has been removed. It is bagged and placed to TH b2 level south wall beside the silo.

refilled TCS:TK2 to 27.4 inches to compensate water lost during THC filters change.

Chad and I did a pressure test on TM2 tube Heater+(D) water line.I pressurized the D line with shop air from quick connectors(both ends) on service cap.chad applied bubble soap onto the D water block in SHC. The test started from 5psi,and increased 5psi each time to 40 psi. From 5 to 35 psi, no bubble has been found on water block. At 40 psi , bubble appeared from blind blank off seal , but not from soldering joints. Since the o-ring seal for the blank off is  vacuum seal , but not for pressurizing, It is understandable the seal could not hold 40 psi pressure air. No bubble had been found on the D water block soldering joints .See attachment pictures.

Chad and I did the pressure test on TM2tube heater+(D) water  line at SHC with shop air.We tested from 30psi to 80psi on both side of D line. The bubbles were found at 50-55psi on blank off seal in SHC.

 I would like to correct this E-LOG. There is no real  leaking bubble had been found during the whole test according to the information supplied by Chad  Fisher during  this afternoon meeting. I would like to attach some pictures took from TH during this test.

Alignment notes attached for the optics tray for the refurbished tm3 with the new service and source tray.

*Note: Drive screw bracket sheared off during alignment check with source tray. The drive bracket was replaced. The optics tray was re checked. The front element was .015 to left and centered u/d. The rear element remained the same. The center element could not be checked to do the assembly.

On September 18th installation of nSiC#1 was attempted on TM2. As usual, new fasteners were tested previous to insertion into hot cell and employed during installation. the last fastener to be installed was for the circuit D block. The fastener/air ratchet stalled immediately indicating a problem. The fastener was removed and a an attempt was made trying a new spare fastener. That fastener also jammed right away but could not be removed or installed any further.

A breaker bar was employed to achieve more torque and the fastener was able to be loosened, although it would not come completely out, dangling and wobbling like it was free. A claw type bar was used to add slight pressure to the fastener while it was loosened allowing the fastener to undo the rest of the way.

Target was removed and discovered that that insulator supporting circuit c and d blocks was quite broken and that a few chunks had fallen off. It was also notice that boefore the breaker bar had been employed that a piece of ceramic was on the table suggesting that the ceramic had been at least partially broken at the time of removal of the previous target. Also, the threads of the insert for circuit d showed damage an swarf.

Swarf was vacuum claned out of the circuit d thread insert and a machine tap ran through the insert twice.

nSiC#1 was reinstalled with new waterline gaskets and new c and d circuit fasteners with a little bit of the first 2-3 threads lightly coated with vacuum grease.

High current fasteners torqued to 130 in lbs.

 While removing the SiC#42 it became apparent that the multipin guide pin had become loose again and was not allowing the target to dismount from the module.

The multipin shoulder bolts were removed and then the multipin was able to be pried off.

However the NHC manipulator were not able to reach the guide pin to remove it, which would be required before the SiC#43 could be installed.

The target module was then moved to the SHC where the guide pin could be removed and the installation of SiC#43 took place, along with the transfer of the parasitic attachment onto the SiC#43.

This problem seems to suggest that the multipin could use some redesign to ensure smoother target exchanges.

TM#2 with Ta#49 has had its electrical check and was moved to the conditioning station. see the attached pdf for the electrical check details.

The electrical check has been edited to reflect that well the original has been just not the PDF.

TM#1 has been moved from the south hot cell to the north east silo, move went well.

TM#1 moved from conditioning station to the south hot cell, the module had a field of 16mSv/hr.  The move was not without excitement as the crane decided on its own to move 2 inches west on two occasions during the move.On the second time that the errant moved happened I hit the E-stop on the crane kill the power, the first time it happen it stopped the errant movement on its own.

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

Yesterday TM#4 with UCx#5 was moved to the east target station from the conditioning station,  move went well.

TM#2 with SiC#32 has been moved from the west station to the south hot cell.
