On October 22 2024 the spent SIC#44 returned from CNL was repacked in a new pail it was in pail 275 and repacked into pail 298 it was 2.34mSv/hr when removed from the south hot cell.

It was placed in the very back of the mini vault. 

TCS water system has been started for functional test. System parameters including  pressure, all temperature sensors, flow rate sensors, resistivity are ok. I will watch on chiller CP1/2/3 in rest of the week and make sure chiller CP1/2/ 3 auto stage in/out work fine.

 On Friday October 11th TiC#8 and Ta#67 were place in the spent target vault in Tray 8. See attached PDF for details. 

 5 shielding blocks are transferred from ITW to ITE, Target Area is secured again after moving.

 Resolution comment / Commentaire de résolution:

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

A safety walkaround was completed for the ISAC Hot Cells and Target Hall Areas.

The resulting spreadsheet can be found on DocuShare as Document-242733.

Main deficiencies identified:

• Hot Cells:
  • Phone not working at North hot cell operator station
• Target Hall:
  • Uncertain if NHC and SHC ventilation pressure gauges have recently been inspected

Action has been taken on all deficiencies.

 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. 

 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

 TM2 with new target Ta#68 installed is connected in ITE. Pls see form attached.

Tm2 has been moved form SHC to ITE. The move is smooth.

ABCD was dead shorted to 60kv bias during the first time measurement after target installation. Target was removed and reinstalled again with new VCR seals by Ferran.  during target removal process, short disappeared when Aaron remove bolts on CD tube heaters terminal.  leak check and electrical check result are good after second time target installation. 

October 7, 2024 - Aaron Tam 

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

 October 1, 2024 - Aaron Tam 

Ta#67 LP-SIS removed from TM2

Ta#67 is sitting in SHC awaiting PIE 

TM2 Containment Box Cover has not been reinstalled 

Photos of target removal and module attached 

TM2 has been moved from ITE to SHC. Peter did the move with Travis on help.  The move is smooth.

 TM2 with spent target Ta#67 was disconnected in ITE. see attachment pls.

TCS water system resistivity analyzer has been repaired. Two diodes and one capacitor on PS board were broken. They were replaced. Installed analyzer back and tested it in system. it works fine. Operator closed e-fault, removed force on TS5, and enabled alarm on TS5 and TC1.

Tm3 has been moved  from SHC to silo. the move is smooth.

HALCW O2 level sensor annual maintenance is done. sensor membrane has been changed and electrolyte has been refilled. gauge is calibrated. It works normal after the job.

 5 shielding blocks have been moved from ITE to ITW.
