The waterline loop bracket has been installed onto the new loop holding bracket and both installed onto the new source tray.

 TM#2 with Nb#8 has been moved from ITW to the south hot cell.

The heat shield water lines were not purged ahead of target exchange in the hot cell. This resulted in water leaking onto the new target assembly (heat shield) when the cooling lines were opened at top and bottom (for connecting leak detector). Excess water was wiped up with paper towels.

 The west entrance module has been moved from the west target station to the south hot cell, for a bellows replacement.

 Electrical Checks of the last two targets Ta#56 and UC#23

 TM#4 with Ta#56 has been moved from the east station to the south hot cell.

 Results of the electrical check with the spent Ta#56 attached, no target attached and the UC#24 attached. These test were performed on TM#4.

 TM#2 with UC#23 has been moved from ITW to the south hot cell. The shield plug was also installed remotely as well.

 Results of the electrical check on TM#2 with no target after Chad cleaned out the bolt hole on the module where the target mounts.

 TM#2 with the nSiC#1 target had its check done on it at the south hot cell see attached for results.

UC#23 experienced short between target and heat shield as it was heated during operation. The inspection of the target after irradiation revealed that the left target leg was close to the heat shield opening and likely the cause of the short. Marks could be seen on the leg indicating contact. See attached photo. More photos are available on DocuShare

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.

The south hot cell window has been found to be leaking oil. Upon inspection yesterday I found that the bolts compressing the gasket on the cold side were "loose". I have re-torqued them to the specification provided by the manufacturer in the attached procedure.

 TM#4 with UC#24 has been moved from the east target station to the south hot cell.

Tried to leak check TM4 Ta57# at TCS. LD failed to pump down properly at fine range. It always tripped at 4 torr. I cheeked all vacuum lines seals and adapters on top of module to LD. Everything is good. Chad said the VCRs at SHC can not be tightened any more. Discussed with Anders, we decide to move module TCS and helium pressure test there.  The same difficult happened last time on TM4 UCx24# at SHC when leak check. But,it is solved by pressurize the line at SHC last time.  

The HS line was pressurized with 70 psi helium on Oct 04th at TCS.. LD 0,00X E-9atm.cc/sec no change in 2 minutes. No leak.

Cover 1 was removed from the exit module. Confirmed with David that the actuator rod that needed to be disconnected was the far left )as viewed by the hot cell operator). The fastener for this rod was un-accessible from this side. Cover 1 was re-installed (two bolts left loose) and cover 2 was removed. fastener holding the actuator together was removed and luckily it does have a remote start.

ITW RV4S (A and B) are leak checked. They are good. 

Actuator arms, lemos, lemos and banana plug block have been disconnected in preparation for raising of the service tray. Aaron has pictures

 TM#2 with targets nSiC#1 (old target) and UC#25 (new target) electrical check results. See attached for details.

The handle cable on the east manipulator of the south hot cell has been replaced. Old cable showed signs of wear but had no broken strands. Manipulator is back together but still needs to be re-tensioned.
