TM3 window line has been leak checked after containment box removal and installation for insulator installation on water cup C.   No leak.

10 pins lectrical check result after insulator is installed on water cap C.

pin 14 to 60kv bias has 20 Kohm @250V Megga check. The rest check on ohmmeter and megga @250 are either OLor over 25Mohm which are good.

• New window line VCR seals installed
• Dropped bolt from TiC#8 removed
• Containment box reinstalled

 5 shielding blocks have been moved from ITE to ITW.

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.

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

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.

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

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.

 Resolution comment / Commentaire de résolution:

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

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

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.

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)
 

TM3 was moved from silo to SHC with no target. Move successful.

TM3 was moved from SHC to TCS with UCx#47. The move was smooth.

TM2 was moved from ITE to SHC with Ta#68 target. During the move, a railing was lightly bumped by the corner of the module - no obvious damage or issues have been observed. Otherwise, the move was smooth.

TM3 was moved with UCx#47 from TCS to ITE. The move was smooth.

all water lines on TM2 have been purged. Refilled them(except HS ) with 60psi nitrogen for module silo storage before next year using. 

TM2 was remotely moved from the South Hot Cell to SW Silo. Reading at SHC = 89.8 mSv/h. The move was smooth.
