TM2 was moved from ITW to the South Hot Cell with Ta#66 target.

TM2 was moved with no target attached from the South Hot Cell to a silo.

Ta#66 post operation electrical check was done at SHC this Monday. See attachment.

Broken TM2:TP2 has been replaced otday by a new TV-1001 nav pump supplied by vacuum group. replaced pump seris number:201281. new pump series number:IT23431008. TPs replacement history sheet will be updated by Frank. I will put comment on this e fault and let operator to close it.

TM2 was moved from silo to TCS yesterday morning. The move is smooth.    TCS vacuum system was started after. TCS and TM2 pumping down is ok so far.

TM2 is moved from TCS to silo this morning. The move is smooth.

  couple of E-8 to low E-7 atm.cc/sec leak were found on TM2 service cap top air to vacuum  o rings.  Replaced these leak o ring seals including o ring on IG1 and steerer service panel,o rings on MSP, EE, D blue nylon and copper feed through, and o ring on a round blank off beside MSP terminal on second row. 

2024-july-03 update: TM2 was leak checked again at TCS. no air to vacuum leak on module top. i helium pressure tested(60psi) all water cooling lines (except HS) . They are leak free.

Tm2 has been successfully moved from SW silo to TCS.

Tm2 has been moved from TCS to SW silo. the move is smooth.

 Ta#67 Target loaded onto TM2

Leak check passed

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

 TM2 with new target Ta#67 had been electric/leak checked before moving to ITE. See attachment pls.

 TM2 with new target Ta#67 was connected in ITE, all TP are running at their full speed now.

 5 shielding blocks have been transferred from ITW to ITE, MAA has been secured after moving.

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

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

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 

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

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. 

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

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