The target was inspected today.

It was found that the target tube had broken on both sides of the centre block in the region that contain target material. The Ta-foil heat shield was removed from the let side tube to allow inspection.

UCx #5 has been moved from the south hot cell to the storage vault. It is in Pail 102, in spot 2A of the vault and had a field of 32.6mSv/hr upon extraction from the south hot cell. See attached PDF for vault details.

Handover from TPO and inspection

• Completed
• Some modification to the center Inner-Outer conductor had to be made (hole enlarged as tab was slightly short)

Target Insertion:

• Successful 

Target Mounting:

•  Upon fully seating UC#47 on service tray locating pins, the gas line VCR gasket came off 
  • Operator doesn't have line-of-sight to this area, so there has to be healthy clearance (Foreshadowing) 
  • Gas line VCR gasket reinstalled using manipulators  

• 2nd seating of UC#47 on service tray locating pins, the gas line VCR gasket came off again
  • Some alignment interference with the gas line coupling is the cause of the gasket falling off during placement (photo attached)
  • Gas line on service tray was loosened, raised to highest position and fastened (Photo attached)
  • Failed to re-install VCR gasket (Plastic separated from gasket material)
• Target removed from Hot cell to reinstall gaskets and make modifications to the gas-line coupling
  • Gas line coil plastically deformed to give less of a spring action so the coupling can stay down under friction until it is time to couple
  • Target carefully inserted into hot cell without disturbing spring/friction of gas-line coupling. 
    • This had to be repeated several times. Once for the waterline gaskets coming off, and a few other times to insert the target/tray without disturbing sprung coupling
• Target mounted without issue after the above steps successfully 

Gas and Water Services:

• VCR connections coupled 
• Leak test passed
  • leak test faster today because module had been left in silo for a long time to dry out. 
• Gas line no-longer needed, so was not checked

Electrical Services:

• Conductor bolts installed
• All bolts (including mounting bolts) checked for fit with mirror
• Coil conductor bolts torqued to at least 130inch-lbs 
• Electrical test completed 

Containment box panel reinstalled 

Cleared area around module for craning out. 

An electrical check and leak check had been done after new target UCx47 was installed on TM3 in SHC. see attachment pls.

TM3 with new target UCx#47 was connected in ITE right after be moved from TCS. 

 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 .

 TM3 with spent target UCx#47 was disconnected in ITE and will be moved to SHC.

TM3 UCx#47 after operation electrical check  is done at SHC. The result is normal. See attachment.

UCx#46 Target handover from TPO 

Target insertion: successful 

Parasitic Install: All Parasitic targets left off target

• Left side In-beam array type parasitic install attempt #1 
  • Parasitic assembly is too thin/studs too tall for the socket nut to fasten onto target. Stud protrudes through the length of socket section, not allowing tool to insert 
  • previously a 3/4 spacer was used to give space for thermal couple to enter 
  • Install of 3/4 spacer was difficult because it does not hold its shape when handled (pivots around 1/2 ad 1/4 portions) 
  • With spacer installed, parasitic assembly is too thick for socket nuts to fasten onto studs. 
    • It may have been possible to back out studs to use, but left off in the interest of time UCx is exposed. 

• Right side In-beam window type parasitic install
  • Similarly to Left side, studs were too short for install, studs could be backed out, but was left off in the interest of time UCx exposed

• PEEK seal parasitic targets were left off as per schedule, and will be leak checked at another date (after tong cable has been repaired) 
  • Order of PEEK seal locations preserved and follows order as seen with target installed (Photo attached)

Target install: successful 

Leak Check: Successful 

Electrical Check: Successful 

• Initially failed due to wiring diagram being different between production wiring diagram and electrical test sheet

Containment box panel closed 

 TM4 with new target UCx#46 was moved from TCS to ITW and has been re-connected right after. see attachment pls.

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

 TM4 WITH UCx#46 was disconnected in 2025-01-02 in ITW. Forms attached.

UCx#46 removed from TM4 and placed into a pail back-filled with argon. Nothing visually unusual; no issues.

TM4 has been moved from SHC to TCS. the move is smooth.

electrical check and leak check were done on TM4 UCx#45 target at SHC.  everything is ok. See attachment

helium pressure test on TM4 HS line at TCS is done.   No leak.

On Wednesday, May 22, 2024 UCx#45 was installed on TM4 in the SHC. Installation was normal other then minor issue with the multipin connector drive screw not engaging and/or driving properly. This was remedied by loosening the left guide bolt slightly (1/2 turn). After loosening the multipin drove in and seated correctly (verified by camera). High current fasteners torqued to 130 in lbs.

TCS was argon vented this morning between 6:00 and 7:30am for TM4 moving to ITW.

Tm4 has been moved from TCS to ITW.  the move is smooth.

 TM4 with new target UCx#45 was connected in ITW this morning. pls see attachment uploaded with.
