The testing of the mock-up and tooling has commenced.

Source tray mock-up has been driven into the mock-up and the first two water block connections have been made; the first with the torque limiting 
T-handle tool and the second with the torque limiting air rachet attachment. Both seem to work well, although achieving the required torque with the manipulators proved to be near the limit of the manipulator.

The source tray for the mock-up has been setup for waterline bending and soldering/brazing.

Thanks to Travis for finding the photos for the TM3 rebuild that took place in the anteroom in 09' and Maico and Dan for the support in ironing the issues with the source tray side soldering issues.

The Mock-up has been leak tested after the remote connection of the water blocks and is leak tight!

Thanks everybody who contributed to its success.

All water block connections on the mock-up have bben achieved. It is now ready for leak checking.

The front half of the water block jig proved extremely difficult to remove.

Remote capability was added for the mini-storage door control. The control signals originate from the Opto 22 Module box that is used for the SMP remote control (this is located just above the storage vault).
The controls signal assignment document has been updated and can be found in C:\PDM Vault\PDM_Vault\_models\isac\isac1\wpn-3919 - safe module parking\Electrical

In order to operate remotely:
- Plug the mini-storage control box power cable into a wall outlet (adjacent main storage vault, under stairs)
- Plug the motor output cable into the mini-storage door motor
- Unplug the local pendant from the box
- Plug the cable that comes from the remote module box into the connector that the pendant was plugged into (M12, 5 pole Murr connector)
- Using the remote control program from the ISAC RH control room, click on the Mini-Storage option and then click buttons for open and close to operate the door (note: it is important to verify both opening and closing functions work before attempting any remote operation).

Remote and local functionality have been tested and verified working.

It is recommended to mount the mini-storage control box in a convenient area near the mini-storage (possibly on the wall adjacent the main storage vault).

Please contact me if you have any further questions.

A cable track was installed between the mini-storage vault and the silos, for the purpose of implementing a retractable cable chain (e-chain). This will allow for cables to be managed during door opening/closing, so that remote control operation of the door will be possible in the future. See Work Permit I2021-08-11-2 (Aug 11)

Holes were drilled into the motor mounting plate (IRH2089) to allow for mounting a limit switch on the plate. See Work Permit I2021-08-17-7 (Aug 17)

Preliminary testing was completed in which the e-chain was fixed to the door with a C-clamp. Local and remote functionality were checked, and limit switch functionality was verified. Everything is working as expected. A final test will be conducted once the e-chain is fixed to the door and cabling routed through it. See Work Permit I2021-08-19-1 (Aug 19)

The e-chain has not yet been fixed to the vault door - holes will be drilled in-situ after preliminary testing is complete to confirm positioning.

 Edit [2021-09-23]: the installation is complete and has been tested.

 Mini Vault Door as some difficulty over coming a small hump on its track. To open the door one needs to give the door  a slight tug while it is opening to over come this hump.

The bearings on the mini storage vault were lubricated. It is suspected that this has never been done. It is suggested that this be performed every two years.

A draft procedure will be created for this job, but at a high level, this process involves:

• Opening the door fully
• Disconnection of the motor, limit switches, and cable management system
• Attachment of a lifting magnet to the door itself
• Raising the door
• Lubricating bearings
• Reversing the process to re-assemble

The entire job took less than 1 hour to complete.

In an effort to clean up the camera installation on top of the ISAC target hall crane to resolve a fault, the position measuring tape and its associated camera were removed from the target hall crane on July 31, 2023.

Still to do: clean up power bar installation.

I've taken measurements between HV and ground circuit on TM2 source tray as instructed.

At their closest points:

Heat Sheild to Ground Electrode 0.445"

Ground Electrode to C1+ 0.281"

Window to Mounting Support Plate 0.858"

On May 16th 2013 the module was HV conditioned all day. As a result the maximum stable voltage has been increased to about 47kV (~4kV more than last test). A maximum voltage of 49kV was achieved but the module was very unstable. Attached is the data from the testing. Note that occasionally the sparking caused the PS to reset, it was turned back on and the voltage increased back to what it was (or lower) quickly.

Broken tong cable on SW manipulator (serial #8106) of SHC was replaced today.

Following ISAC Hot Cell entry procedure, Document 157554, SHC was entered and wrist and tong cable were replaced with a pre-run/assembled wrist, cable and tong. It is standard to try and pre-make/load a new cable into a spare tong assembly to reduce time spent in the HC. This marks the first time a wrist has been replaced. Rationale for replacing the wrist at this time is that internal spacer A-14118 which the ting cable rides over has had grooves worn into it. This is a result of regular wear and tear but could be causing premature wear on the tong cable. Replacement is a preventative measure. This is the original wrist and spacer from the original install in 1998. The wrist that was removed will be rebuilt and swapped out with the original one on the SE manipulator (serial #7986) at a later date.

Parts replaced today are: New - Bottom half of wrist joint (CRL-13950), New - Tong cable (CRL-14230) and used tong assembly (CRL-18062)

Procedure took about 40 minutes. Dose received was ~0.046 uSv

The east manipulator handle has been adjusted and is ready for use.

Broken handle cable of east manipulator has been replaced and manipulator is operational again.

South hot cell was entered to check to replace cable if needed. Wrist cable showed no signs of fraying or broken strands.

A tong with new cable pre-installed is now in the hot cell for next time this job needs to be done. There is also another spare tong cable not installed in a tong located in the box of manipulator repair equipment located inside the hot cell.

Both manipulator slave ends were lubricated whilst inside.

Rebuild handle of manipulator serial 7986 (currently in the east position) and replaced broken snap ring 5555-18h on west side of the handle underneath motion switch.

Tuesday, June 26 the broken tong cable was replaced on the west manipulator in the south hot cell. Wednesday the tong cable was preemptively replaced on the east manipulator of the south hot cell.

Maico entered the hot cell and re-strung the skipped cable back onto the pulleys this morning. Manipulator is now operational.

Manipulator has been sucessfully repaired. Recieved 0.19 mSv. Took Approx. 10-20 minutes

The broken cable on the east manipulator has been replaced.

The handle will need some adjustments which will take place first thing tomorrow.
