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

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.

TM2(SiC nano) has been disconnected in ITW. See attachment

 ITW Exit #2 has been moved from the west station to the south hot cell for a bellows repair.

 The various electrical check done on TM#4 after the UC run and before the start of the Ta run.

TM4 has been connected in ITE. see attachment.

 TM#4 with Ta#57 has been moved from the conditioning station to the east target station.

TM4 Steers 4 pin feedthrough CF flange is replaced due an inside feed through insulator broken. CF 25 cooper seal is replaced with a new one as well. Travis did anelectrical check. after replacement. Everything looks fine.

Note only a megger check was performed on the affected steering lines. Open load was measured on all lines. (Travis Cave)

 UC#24 has been moved from the south hot cell to the spent target vault. The target is in pail #171 and placed in spot 4C. See attached PDF for details.

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.

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

TM4 was disconnected in ITE yesterday. See attachment for checklist.

 TM#3 has been moved from the conditioning station to the centre east silo. This will be its new home after the silo switcher-roo.

I did a HV test on TM3 at TCS yesterday. HV Ramp up speed: 1KV per 5 minutes when below 30KV,1KV per 10 minutes from 30-36KV. There is no major spark below36 KV .  I could see  lots small and big vacuum response on IG1 and PNG2 when conditioning from 30-36 KV, especially when closing to 36 KV.  However, At 36.4 KV, There is a big continuous spark occurred. It could not be stopped until I lowed the HV to 14KV. I have to ramp up from 14 KV again.  This behavior on TM3 HV test is same as before we saw. The module can not pass 36KV at present condition.  During the test., EL is tied to 60KV bias. The HV cover on TM3 top is installed. And, Service tray  cover plate is installed on TM3.

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.

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.

water loops are by passed on top. All bias, EE, and  EL are tied together. Started water system.

 The spent UC#23 target has been moved from the south hot cell to the spent target storage. It was placed in pail #170 and place in spot #4B in the vault.

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

Tm2 with SiC nano has been connected in ITW. See attachment for checklist
