Aaron Tam | South Hot-Cell | Standard Operation | | Ta#68 | Ta#68 PIE |
Abstract:
This target has seen some irregular beam patterns
Possibility that the beam hit the walls of the target tube or even the cooling fins
This PIE we want to investigate how the irregular beam physically affected the target
Related ELOGS:
ID: 2728
ID: 2698
PIE was performed by Aaron Tam, Directed by Aurelia Laxdal, Observed by Lucas Backes, Special help from Chad Fisher
External views:
- Windows are clear of any irregularities
- More pictures of this can be found in RH-ISAC E-log 2728
Internal Views:
- Heatshield internal
- Some discolouration from heat and soot deposits.
- This seems to be fairly clean to normal amounts - not concerning
- Target tube
- tube is bent with the middle higher than the sides
- Target tube was not removed 9/64ths allen wrench could not be located for this operation
- Target tube Exit
- Heatshield windows were punctured to reveal the target tube entraces/exits
- Entrance is waterline side (ITE)
- Extraction electrode parts were removed from the back off the target
- These parts look normal
- some of the extraction electrode would not pull out due to tight fitting parts and the investigation stopped here.
Conclusion: Target physical condition is normal as far as we could investigate |

Aaron Tam | South Hot-Cell | Standard Operation | TM2 | Ta#68 | Ta#68 Removal |
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

Aaron Tam | South Hot-Cell | Standard Operation | | TiC#9 Parasitics | TiC#9 Parasitics Leak Check and removal from hotcell |
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

Aaron Tam | South Hot-Cell | Standard Operation | TM3 | UCx#47 | UC#47 LP-SIS w/ gas Install |
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:
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.

Aaron Tam | South Hot-Cell | Repair | | | SHC West Manipulator Repair |
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)

Aaron Tam | South Hot-Cell | Standard Operation | TM4 | UCx#46 | UCx#46 Install and Parasitic Target Status |
November 6, 2024 - Aaron Tam
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
