ITE and ITW water system paddle wheels and coils on all flow sensors in pits have been replaced. It's a SAS job.

Tm3 has been moved  from TCS to silo. The move is successful.

A parasite target has been transferred from SHC to NHC. It is a job to reduce SHC field for coming SHC entry job. The transfer is successful.

 David and I cleaned both cages in ISAC1 electric room, all done.

ITW/ITE pit general annual cleaning up were done. all concrete floor and TM equipment surface are vacuum  cleaned. HV cage inside and blue nylon insulators were wiped by paper.

Today (2025-01-20), six flasks were loaded in preparation for shipment with the following targets: C#4, TiC#5, Ta#64,Ta#62, Nb#10, SiC#44

Some of the pails (256, 273, 279, 277) required replacement of the wire rope cable with new style, 30 ft length, as requested by CNL. A lifting label was also applied to these pails. Some of the pails (295, 298) already had the appropriate cable and lifter label.

At the time of writing this log:

• The second crimped lifting loop has not yet been applied to each pail.
• The locks have not yet been applied to the flasks.

The mini-storage vault is now EMPTY. The mini-storage vault has been swiped and checked for contamination.

The target index spreadsheet has been updated (attached).

A complete TM3 electrical check at TCS under good vacuum has been done. Pin 14 to 60KV only has 8K ohm on ohmmeter check , and it's about 2Kohm @250V Megga. It's low in resistivity. The pin 14 is for thermocouples only so no big concern.  The rest things are good. See attachments.

 The spent UC#47 was moved from the south hot cell to the spent target vault placed in pail #302 in spot 1C of the vault, it was 24.5mSv/hr when removed from the south hot cell. See attached for vault details.

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

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

UC#46 was placed in pail# 301 in spot 1B and was 26.3mSv/hr when removed from the SHC. See attached PDF for vault 
details.

 SMP:MP1 is started with SMP BV1 is opened. SMP is under vacuum for TM4 storage during shut down.

ITH:MP1 is deteriorating by watching on ITH:CG1 and CG2 readings and investigation in pit. A fault 17644 has been issued. this pump will be replaced in March when general fielding in vacuum pit is reasonable for the job.

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

ITE primary and secondary vacuum vessel leak check for 2025 shut down have been done. No leak.  The TM3 waterlines helium pressure test will be done at TCS when module is there.

TM3 water lines helium pressure test  are done. 70 psi helium 3 minutes to each line( except HS which has no target on it ) . leak detector base leak rate :0.0Xe-9 atm.cc/sec. No leak on all tested water lines.Helium were purged out after test. and 60 psi nitrogen were filled in lines for storage. 

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

 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 .

ITW primary and secondary vacuum vessel leak check for  2025 shut down has been done. Also,TM4 internal water line helium pressure test has been finished.  Both results are normal. There are two small old leak on EXit 1 and Exit2 module top plate  o-ring under 1Xe-8 atm.cc/sec which we knoew in past years test. resin spray on leak  area reduce the leak ratee below 5Xe-9 atm.cc/sec. No concern on these small leak.   See attachment  for detail results.

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:
  • NHC right manipulator gripper stuck (known, repair planned)
• Target Hall:
  • 50% of overhead light bulbs burnt out (David Wang contacted Electrical Services to rectify)
  • One RH camera for target pit not working (Travis Cave notified)

Action has been taken on all deficiencies.

An informal inspection of the main Pail Handling Tool was performed today as the final one for the year. Note that the main formal annual inspection was performed June 18, 2024 for this year.

The attachment to this e-log serves as a record of all inspections for this tool throughout 2024.

The spare tool was not inspected as it was not in service this year.
