Ta#67 Target loaded onto TM2

Leak check passed

Electrical test passed after loosening off target electrode conductor screws, and torqueing by feel 

 SiC#46 loaded into pail 293 successfully along with other hotcell waste 

Upon visual inspection of the target, a spark-sign was spotted on the perimeter of the extraction electrode. Metallic looking material also found built up between the extraction electrode and the backing plate of the target

• Plastic and clean target tray added to SHC 
• TM4 moved to SHC 
• TM4 containment box cover removed

September 6, 2024 - AT

• Ta#68(Spare) removed from TM4 onto clean tray 
  • top left mounting bolt fell under source tray in containment box - unretrievable
• Ta#68(Spare) moved out of SHC via toolport door 
  • SHC lift table was lower than tool port tunnel by 2". Target-on-Tray slipped back onto lift table when trying to drag it up to the tool port. Target bounced out of one locating pin, but stayed within boundaries of the tray 
  • Water also leaked out from the VCR fitting and on to the SHC lift table, and toolport. 
• Target-on-tray slid into a clean plastic bag, and then into a plastic box. 

 September 9, 2024 - AT

• Ta#68(Spare) taken out of plastic bag and water drained from waterlines
  • Target was rotated in every direction several times until no more water poured out from the VCR joints
• Ta#68(Spare) put back in box without the bag (to promote evaporation) 

September 9, 2024 - Aaron Tam 

• Water from waterline found puddled on source-tray and containment box. 
• Water was wiped up as much as possible, but likely still in containment box 
• leaving to dry overnight
• Target inserted into Hotcell with nuts for the parasitic target. 4/4 socket nuts installed on upstream flange, and 3/4 installed on downstream flange

Ta#68 HP-SIS checks performed at B1 lab, moved to anteroom, and inserted into SHC via tool port w/ Aaron Schmidt. 

Ta#68 fixed to source tray with 4 mounting bolts in order of: Right manip. holding, Top left, Right manip. removed, Bottom right, Top right, bottom left. w/ Aaron Schmidt and Brady Borrmann

• Motion was smooth, no resistance when positioning onto pins

VCR fittings done up with ample force, leak check passed

Conductor bolts installed in order of: 2 Target electrode conductors (Checked washers), 3 target Inner and outer conductors.

All bolts checked for full contact with mirror and binos. 

Electrical check failed: Dead short (look for David's ELOG for more detail when available) 

Troubleshooting while David is checking resistance: w/ Ferran

• Intermittent success with heavy manipulation of water lines
  • Loosening off Waterline bracket-to-source-tray 
  • Loosening off Bracket to water line bolts 5/32 hex's 
  • Rotating bracket towards operator (effectively raising waterlines in the back upwards) seems to yield more intermittent success, but never passing megger @ 250V 
  • Tube was inadvertently dented when handling the tube in a wrenching motion with manip tong. counterclockwise
• Target removed while David is still on the multimeter (calling for any sign of success)
  • Starting to remove Target in order of: Tightening back waterline-to-bracket 5/32 hex screws, loosening off waterline bracket, loosening off VCR nuts, 2 Target electrode conductor bolts, 3 Target inner and outer conductor bolts, Fixing bolts Top left (dropped below source tray), Bottom right...
    • (At this time David called with some success with electrical check)
  • Reversing course to verify fault has passed, target was reassembled, only finger loose on the VCR nuts.
  • Faults no longer present
  • Target removed
    •  As target was being pulled off source tray locating pins, a piece of ceramic fell onto the source tray just behind window waterlines.

Target taken out of Hotcell by Ferran. New VCR gaskets installed. Target reinserted 

Target installed no issues. Used fixing bolt used to replace dropped one. 

Leak check passed, Electrical check passed

• Notably don't have a photo of reinstalled target or source tray before 2nd install attempt. 

Containment cover reinstalled 

Ceramic piece moved into Pail #285 (suspect this is a very hot piece)

TM2 ready for move to ITE

 Post Irradiation Examination

October 9, 2024 - Aaron Tam w/ Chad Fisher, Aurelia Laxdal, and Lucas Backes 

PIE conducted by Chad with direction from Aurelia. Aaron and Lucas observing/documenting 

Goal: Thin foil target material is somewhat novel, and we should characterize the differences if there are any. 

Photos of the pre-examined target can be seen on ELOG 2697  on Tuesday October 1, 2024, when the target was removed from TM2

Notes:

• Right most inner/outer target conductor bolts was sitting proud and had threads showing, photo attached
• Some Black deposit was found on the inside of the heatshield directly below the extraction tube, and loose in powder form inside the heatshield. 
• Target tube seems to have more of a crystalline texture than previous examinations.
• When Target tube was being removed, one of the target electrode conductors broke off
• some dimple texture was found on the target tube windows and this was further explored by prying a channel through the length of one side of the tube to get a better look

Target pieces were placed loosely back within the heatshield, and the lid loosely placed back on.

Awaiting pail loading, and move to storage vault

 Post Irradiation Examination

October 9, 2024 - Aaron Tam 

Goal: Training (First PIE by Aaron), Characterize any anomalies 

Notes:

• Overall the target looks exceedingly clean with only some discolouration on the copper behind the target tube, and multipin cable insulation. 

 Resolution comment / Commentaire de résolution:

     Fixed issue by changing patch cord that was connected to the switch from patch panel.

TiC#9 HP-SIS removed from TM4

• Top left fixing bolt shows signs of heating on it (Comparison photos attached Bolt_profile.jfif  & Bolt_Tops.jfif)
• Location and orientation of darker bolt (Darker_bolt.jfif)

Parasitic Targets Removed

• Left target has residue left from ablation 

See photos attached for detail

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

Tong cable snapped when attempting to remove multipin connector bracket 

Assistance from Chad required for the rest of procedure 

Tic#9 was loaded into Pail#299 

• Along with fixing and conductor bolts (no other material was loaded)

 November 14, 2024 - Aaron Tam w/ Chad Fisher 

Following ID: 2716   
"Nov. 8, 2024 - Aaron Tam 
Tong cable snapped when attempting to remove multipin connector bracket"

Repair went as follows:

• weighted clip attached to tong return side to tension/keep tapes on pulleys
• Manipulator was pinned from both sides (Pinning from master side first makes it easier to position slave side)
• clamps were used to suspend all tapes and cables near the relay bracket 
• extension tube limit clamps were moved to the top to stop it from dropping when Z motion tapes disconnected
• Z motion tapes/tension adjusting screws taken off master carriage and suspended with equalizing weight ~10+ lbs)
• Extension tube limit clamps and extension tube lowered give space to expose multiplier later 
• Wrist joint and handle removed as a unit 
• extension tube to multiplier screws taken out
• Extension tube raised to expose multiplier - using extension tube to wrist joint positioning clamp to keep it in place 
• Old cable removed
• new cable installed

installation in reverse with spare master handle 

Notes:

Spare master wrist joint was missing gears that connect wrist drums 

• this had to be disassembled and installed with gears from old wrist joint

Handle ratcheting pawl spring was not oriented properly, so this had to be disassembled and reinstalled properly (in the process one spring was lost Part#: A-5800)
 

 November 26, 2024 - Aaron Tam 

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. 

 November 27th, 2024 - Aaron Tam with Farran & David 

Parasitic Assembly Leak Check (Aaron, Farran, David)

-Note that the furthest upstream (right of the target) parasitic top cap screws had been loosened and retightened in error when attempting to remove it off TiC#9

-This puts this data point into question 

-Leak check starting from upstream to down stream 

-First parasitic had no leak 

-Second parasitic had some leak 

-Third parasitic was not pumping down at all

-First parasitic checked on test hose again with same success

Parasitic Dis-assembly (Aaron) 

-First parasitic had good tension in all 3 screws

-second parasitic had 2 screws with a perceptible breaking-loose of the screws, but one was imperceptible 

-Third parasitic had lower (than first parasitic), but okay tension in all 3 screws 

In an attempt to move the PEEK seal into a safe spot with tweezers, this one was accidentally sprung across the hotcell in the direction of the tool port 

A lengthy attempt to find it was conducted, but no PEEK seal was recovered 

This may effect our ability to do work during hot cell entries coming up. 

PEEK Seal extraction (Aaron, Farran) 

-A labeled bag was inserted into the hotcell via the tool port and onto an existing tray in the Hotcell

-PEEK seal placed inside bag, placed back on tray, and moved back to the tool port for extraction

-With tool port open, the draft was able to push the bag across the lift table. Changing the cross section exposed to the draft works to keep the bag from moving

-Farran used picker to extract the bag into the tool port where he wiped and placed into separate bag.

-This process was repeated for the second PEEK seal 

-Bags were wiped and swiped, put in another bag, swiped and brought over to Hot cell Service area Lab 

  Note: Ta#68 had a difficult install. See E-log ID# 2698 for more info 

First look:

• Containment box cover looks the same as previous (See:ID: 2697)
• Target shows large amount of soot-like deposits (See photos for locations)
• Deposits seem to have been left on parts of the service tray as well ie.: Multipin connector 

Removal:

• Removal was smooth
• Water-line bracket fixing bolts seemed loose even before I put a tool to them 

Eyes of sides:

• Better photos of where deposits are 
• Everything else seems normal
