Tuesday, June 23, 2015, 14:19, chad fisher, South Hot-Cell, Repair, TM2, , TM2 Water Block Jigs Removed
|
Both halves of the water block jigs have been removed and the module is now ready for base vacuum leak and electrical checks.
During removal of the jigs the fiberglass that had been "shoved" by hand in between two of the lines in the early 2000's fell out again. |

5 shielding blocks have been transferred from ITW to ITE. The ITE is configured to take proton beam. |
Friday, June 19, 2015, 11:43, David Wang, ITW, Repair, TM1, , ITW external water leak on dump circuit 6x
|
There was an external water leak in ITW during the last beam running time. The leak started after the shielding blocks transfer(May 22). It cause a constantly water level drop on S-tank(0.5 "/day average). Today , after the blocks are moved , the leak source has been found. Water seeped through a fitting on ITW dump circuit pressure gauge. The leak water slowly flow around the TM1 on the tank flange. most of them are dried out, but left some stain on dump module and tank flange. By closing the supply and return water valves on the ITW dump circuit, the leak is stopped now. We will fix this problem after the module is moved out and the radioactive field is low. See attachments. |
Friday, June 19, 2015, 09:37, Isaac Earle, South Hot-Cell, Repair, TM2, , TM2 Source Tray Installation - June 18, 2015
|
The following work was done on June 18 2015:
- Finished cleaning and polishing all water blocks on module side (white felt with isopropyl, then buffing material with isopropyl, then canned air). Heat shield waterblock re-done because water marks visible (white scotchbrite, white felt w/ isopropyl, buffing material w/ isopropyl, then canned air). All surfaces looked very good, no lint or scratches visible.
- Tray installed using installation jig (jig was very difficult to slide on hot cell table). Window circuit waterline bracket tube retaining screws had to be removed for the sourcetray to clear the module frame. Optics tray locating mushroom on source tray rubbed against the module side waterblock jig and was pushed past. Gas lines were held clear of the source tray with the manipulator as the it went in. The nut on the source tray side water block guide pin had to be loosened to facilitate complete insertion of the source tray.
- Connection of waterblocks for circuits D, C, B, A, Febiad Coil 2 were done in the sequence listed with no issues
- Extraction electrode and heat shield water blocks could not be done up initially because the locking tabs could not be undone (interference with module side jig bracket)
- Ground electrode waterblock connected without issue
- Window waterblock attempted: screws would not engage
- Febiad coil 1 negative waterblock source tray side locking tab had to be re-inserted into block, then waterblock was connected
- Febiad coil 1 positive connected without issue (failed initially due to shorter screw)
- Mounting support plate waterblock alignment pins did not engage initially, rotated source tray side waterblock using polishing tool. Then was connected without issue.
- Extraction electrode waterblock revisited: pulled together with 1-5/8" screw, then connected (with 1-3/8" screws in both holes as per ITA6144)
- Heat shield waterblock revisited: installed without issue (as the jig had been pulled together by the previous step)
- Attempted window water block again. Right side manipulator wrist tong cable broke while using camera. Waterblock could not be connected (holes look concentric, pins engaged, blocks together and almost flush)
- All waterblocks except window waterblock torqued (tool did not slip properly, so torque will be re-checked)
Plan for Friday June 19:
- Put blank-offs and various fasteners in hot cell through tool port
- Check torque of all waterblocks with dial torque wrench
- Attempt window water line again with different fasteners (non-blunt start), try removing both sides of waterblock alignment jigs
- Install blank-offs on window and heat shield lines (VCRs)
- Perform preliminary leak check |
Thursday, June 18, 2015, 08:03, chad fisher, South Hot-Cell, Repair, TM2, , TM2 Optics Tray Transfer
|
The TM2 optics tray has been transferred from the source tray to the transfer fixture in preparation for installation of the source tray into the module. |
Wednesday, June 17, 2015, 14:21, chad fisher, South Hot-Cell, Repair, TM2, , TM2 Waterblock Clean Polish
|
Fiberglass that fell out yesterday was put back in place (as well as possible).
Cleaning took place this morning with excellent results. Cleaning was performed with red scotch brite on the cleaning tool, air pressure at 40 psi while running, with one 60 second cycle. Three blocks (EE, HS and Window) needed a second pass to remove the indium.
Polishing commenced with 2000 grit wet sand paper. Paper was wet with isopropynol. 60 second cycles for double seal blocks, 30 second for singles. The 2000 grit pass was completed.
Polishing will finish tomorrow morning as well as removal of optics tray from source tray in preparartion for insertion of the source tray into the module tomorrow afternoon or Friday morning.
First picture is Tube heater Circuit D block before cleaning and second picture is after cleaning.

Tuesday, June 16, 2015, 14:28, chad fisher, South Hot-Cell, Repair, TM2, , TM2 Source Tray Installation/Water Block Sealing Surface Clean
|
Today cleaning and polishing pads were inserted into the hot cell.
Module side waterblock jig installation was attempted however one of the locking tabs/latches (ITA2405?) came undone/fell off. Luckily, I had old, obsolete jigs in the hot cell so I was able to remove parts I needed from an old one and rebuild the current one.
Jig was installed on module to retain module side waterblocks.
Blank-off remove was commenced, however due to and large amount of water coming out of the line to have the blank-off removed work had to stop till the water evaporates.
Waterblock sealing surface cleaning and polishing will continue tomorrow.
Also, upon installing the jig a piece of fiberglass that had previously been manual inserted between two of the water lines (early to mid 2000's) fell out. |

|
TM2 new source tray has been remotely transferred into SHC successfully. The transfer table has been moved back to TH within 1 hour. I swiped the table and found about 150counts contamination. It is much better comparing to last time using since we removed this table out of SHC as quick as we can. The table will be cleaned with windex after Target Hall is surveyed. |
Friday, June 12, 2015, 07:49, chad fisher, Assembly/Bench Test, Repair, TM2, , New TM2 Source Tray Ground to HV Measurements
|
After bending and leak checking the new measurements from ground to HV on the TM2 source tray are:
Ground to C1+ 0.6645"
ground to heat shield 0.506
Window to mounting support plate - unchanged - over 0.80" |
Thursday, June 11, 2015, 13:43, Dan McDonald, Assembly/Bench Test, Repair, TM2, , Leak check following tweaking of cooling line gaps
|
Maico, Chad and I conducted a leak check on all affected lines following tweaking of cooling line gaps. All lines pumped down to a level of 10-9 torrliter/sec with no leaks detected with Helium. |
Thursday, June 11, 2015, 13:11, chad fisher, Assembly/Bench Test, Repair, TM2, , Measurements beyween ground Plane and HV TM2 Source tary
|
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"

Wednesday, June 10, 2015, 16:49, Grant Minor, Assembly/Bench Test, Repair, TM2, , TM2 New Source Tray - *HOLD* on installation into Hot Cell until HV approval
|
Don Jackson brought to my attention some potential HV minimum spark gap issues with the source tray cooling lines. It appears:
- The gap between the Ground Electrode cooling lines (ground) and Heat Shield cooling lines (HV) does not meet the spec of 0.668" MIN called out on the print
- The gap between the Window cooling lines (ground) and the Mounting Support Plate cooling lines (HV) does not meet the spec of 0.668" MIN called out on the print.
A copy of the tube bending drawing is attached with the spec highlighted in green.
The 0.668" MIN gap spec came from a check I asked Mark Llagan to perform to find the minimum gap when he was preparing the model for the tube bending drawing. This gap was approved Jan 28th, 2015 by Friedhelm Ames on ECO-3587.
The source tray with the tubes bent as it is currently has been tested to 55 kV at the test stand by Anders, see:
https://elog.triumf.ca/TIS/Test-Stand/447
I am away June 12th to June 24th on vacation inclusive. Isaac Earle is in charge of Remote Handling in my absence.
I am delegating Don Jackson responsible for resolving this TM2 HV issue, collecting and documenting the approval to proceed from the T/IS group leader with the source tray as-is, or to try to re-work the cooling lines and delay the project.
The source tray is NOT to be installed in the Hot Cell until this issue has been resolved.
Regards,
Grant
