Thursday, May 25, 2023, 13:10, David Wang, Conditioning Station, Maintenance, TM2, , TCS MP1 is replaced due to poor performace.
|
TCS MP1 is replaced due to poor performance( system shows unstable and high reading on TCSCG1A and high TP1,TP2 current draw) . The pump is edward 15i scroll pump. Since vacuum group has no same spare pump, i have to use SMP roughing pump SMP:MP1 which is a same pump to replace it.. After the replacement ,the TCS:CG1A and TP1, TP2 current draw are back to normal. The original TCSMP1 was surveyed. Swipes on intake and exhaust port are 300 counts and 1000counts. RAM contact field measurement are from 0.2 to 0.5 usv/hr. It is stored in TH. We will try to refurbish this pump first and use as for SMP:MP1. If we can not refurbish it, a new 15i pump will be purchased for SMP:MP1.
2023-05-31: Opened pump tip seal chamber and swiped chamber inside. The contamination level :1200 counts on 44-2. The tip seal and tip seal chamber o ring need to be replaced . Checked gas ballast knob. The O-ring inside knob is in good condition. Checked exhaust port o-ring. it is in good condition. spare part PO will be issued soon.
2023-06-14:Tip seals and o-ring have been replaced on original TCS:MP1. After, it was tested at TCS for 48 hours. The pump is much quiet on operation, and the pump body temperature is mild. The final inlet pressure this pump could get with TCS PV1 closed is about 23 mtorr. The result is good. I installed it back to TCS vacuum station and reinstalled SMP:MP1 back to SMP vacuum station.

Tuesday, June 06, 2023, 15:10, Antoniette Yap, Spent Target Vault, Maintenance, , , Annual Inspection of Main and Mini Storage Vaults
|
The annual inspection of the mini-storage vault and main storage vault was completed June 23, 2023. The following items were checked:
- Cabling and cable management
- Connectors
- Controls box - internal wiring and components, functionality
- Limit switches - functionality, wiring, mounting
- Motor
- Bearings
- Set screws
- Miscellaneous fasteners
The inspection was generally successful. A couple of minor findings were:
- Bearings for both the main and mini storage vaults must be greased. This is planned for a different day as it involves removing the mini vault's door.
- There was a small piece of metal on the track for the mini storage vault which was causing the door to "bump" over it as it passed over. This piece was removed and the door behaved normally.
- The wheel track for the main storage vault was dirty - it was cleaned
- It was suggested that the 120 VAC power cable for the mini storage vault controls box should be connectorized - this will be added to the "to-do list" for the future

Tuesday, June 20, 2023, 12:37, Adam Newsome, Assembly/Bench Test, Development, , , Modifications to wire ropes for pails within existing F-308s 6x
|
Based on a request from CNL (attached), modifications were made to the wire ropes protruding through the tops of F-308s to add a crimped loop which acts as a lifting feature. Tests were performed (report attached) on 10 sample units to validate the strength of these loops, since each loop could not be tested in-situ once the pails were already packed in F-308s. CNL has reviewed and approved the test report.
Wire ropes within the following F-308s, which were staged for shipping as of June 20, 2023, were modified to include the lifting loop:
- 06
- 13
- 15
- 16
- 19
- 20
- 21
- 22
Each lifting loop was:
- Crimped according to the same procedure, using the same parts and tools, as the 10 sample units
- Measured using a tape measure to confirm the 3" size specified by CNL
- Checked using a go/no-go gauge provided from the crimp tool manufacturer
- "Pull tested" by hand as a quick check to confirm the crimps were successful (not a quantitative and official test, but a secondary qualitative "feel good" check)
As of the time of writing this e-log, TRIUMF believes these F-308s to be ready to ship. |
Wednesday, June 21, 2023, 14:39, Adam Newsome, Safe Module Parking, Maintenance, , , Annual electrical and mechanical inspection of Safe Module Parking  
|
An annual electrical and mechanical inspection was performed on the SMP today by Adam Newsome, Travis Cave, Eric Lahe, Maico Dalla Valle, Antoniette Yap, and Jason Zhang as per Work Permit I2023-06-21-4. The following items were checked:
- Check condition of wiring for physical/radiation/UV damage
- OK, no signs of significant damage
- Check for cable tray debris or damage
- There were multiple items in the cable tray which do not belong there - misc. pieces of wood and metal... these items were not disposed of but should be in the near future
- Check inside control panel: components and wiring, labeling
- Labeling intact, components in good condition
- Misc. random wires pulled to check... one ground wire was loose - it was tightened
- Verify camera views
- This was not inspected in detail but signal status was checked, and is checked prior to remote operation
- Check connectors for damage
- Check pendant for damage and verify labeling intact
- Lid open/close test
- Lid was opened and close multiple times - smooth operation, no concern
- Lid close logic was checked - OK
- Vessel rotation and limit switch check
- Both CW and CCW limits were checked, functioning
- No concern on rotation - chain drive, rotary limit switch, and cable reel all functioning normally
- Lubricate chains
- Not done - should be done next year
- Inspect tensioners
- Tighten fasteners
- Not all fasteners were checked - washers will be replaced soon so this was not deemed necessary
- Approximately 50 washers are missing for socket head screws in slotted parts. Not safety critical but they should be replaced soon.
- Visual inspection
Overall the inspection was successful. |
Friday, July 28, 2023, 10:09, Adam Newsome, Spent Target Vault, Maintenance, , , Main Storage Vault: Bearing Lubrication
|
Bearings for the main storage vault door were lubricated on 2023-07-28. It is unknown when this was last done. It is suggested that this be a recurring maintenance task every two years. |
Friday, July 28, 2023, 10:21, Adam Newsome, Spent Target Vault, Maintenance, , , Mini Storage Vault: Bearing Lubrication
|
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.

Tuesday, August 01, 2023, 09:06, Adam Newsome, Crane, Development, , , Measuring Tape and Camera Removed from Target Hall Crane
|
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. |
Thursday, August 03, 2023, 12:24, Jason Zhang, Crane, Development, , , Cleanup of camera installation on target hall crane, installation of replacement laser  
|
The cleanup of the ISAC Target Hall crane and installation of the new SICK laser which replaced the IBEO laser for the EW crane position was completed on Aug 03 2023.
The clean up tasks which were completed: (Removal of tape viewing camera, Removal of tape, Installation of extension cord, Consolidation of power supplies for the lasers and removal of old laser)
Currently power bar is still present to act as an extension cable. This will be removed when 2m extension cord is made and put in next target exchange cycle.
The installation and testing of new SICK Laser:
1. Calibration points were taken at the 4 corner limits of the crane. North South and East West positions were recorded.
2. Crane was parked at the ladder access position and mounting bracket was machined and installed.
3. A new cable was made and installed for the SICK laser. Continuity test was performed from the control room and crane to ensure pinout of the laser worked with existing serial communication setup in the control room PC.
4. The feedback values from the new SICK laser and old IBEO laser were compared to determine that a calibration offset of 0.06m was needed in the Laser Position Feedback program.
5. Laser Position Feedback program was re-compiled to communicate with 2x SICK lasers with the calibration offset value included in the EW feedback position. (Laser Crane PositionDlg.cpp)
6. Calibration points were taken at the 4 corner limits of the crane again with the new Laser. North South and East West positions were recorded.

There was less than 0.1% variance between the new laser and old laser which is well within the tolerance of the lasers themselves. It can be determined that it was properly calibrated.

Friday, November 17, 2023, 11:28, Adam Newsome, Spent Target Vault, Maintenance, , , Storage vault: issue observed with door opening 
|
During operation today, it was observed that the main vault door had issues opening.. typically when the door was around 80-90% opened, it would stop motion. Note that this issue has allegedly been present since early 2023. It appeared that the motor was still spinning but the clutch was slipping. This issue was consistent and observed multiple times when trays 2, 5, and 6 were engaged (note these are all on the same side of the vault). It was overcome by backing the door up slightly then trying again. The door close function worked with no issue.
It is suspected that there is a problem with the clutch or potentially a piece of debris on the track. [no longer true after 2023-11-17 inspection]
Edit [2023-11-17]: Maico Dalla Valle and Adam Newsome inspected the vault on 2023-11-17. It was very clear that the door, when opening, is rubbing up against the rails. Specifically, the side rollers located on each side of the vault (red housing). There are clear wear marks on each side. The skew is obvious because on one side, the wear marks begin immediately and stop halfway through travel, whereas the other side shows the reverse wear pattern. It is therefore suspected that the skew has become so significant that the friction is too high towards the end of travel which causes the clutch to slip. The travel rails were cleaned (significant grime buildup) and the offending side was filed down slightly (a sharp burr was present from the wear). It is not advised to adjust the clutch. Next steps: open and close the vault with no trays engaged to see if the issue persists (perhaps weight distribution was the issue), and then try different combinations of weight distribution to try to replicate the issue. After this, measure separation distance between guide rails at different points and try to identify the source of the skew issue and rectify it.
Edit [2023-11-20]: Maico and Adam performed further investigation by opening and closing the vault door under 3 different configurations: no trays engaged, 2 trays engaged on West side, 2 trays engaged on East side. The previously observed stopping issue was not observed this time under multiple cycles with each configuration. It is noted that the door appears to slow down slightly and experience a bit of a "chugging along" motion towards the end of travel when opening. Based on these observations, it is concluded that the cleaning and filing helped enough to allow the door to fully travel open/close without getting stuck. The root cause of the issue still remains to be fixed, but for now there is no major concern. Before end of 2023, measurements and planning will be performed to develop a proper repair for the root cause. It is expected that either late 2023 or early 2024, the repair will be attempted.
Edit [2023-11-22]: during a routine spent target exchange, the issue was not observed when opening tray number 2.
Edit [2023-11-24]: a dial indicator was set up on the vault on the right side (looking down from above), mounted on the traveling part with the tip touching the black structural member where the wear is observed. The purpose is to determine how much out of alignment the door is with respect to the structural assembly. The following was observed: approximately halfway through the travel, the indicator read approximately 185 thou of travel. This corresponds to when the wear marks start to occur and where the small red enclosure around the roller wheel interferes with the structural member (causing the wear strip). At this point, as expected, the indicator no longer changes because the roller wheel has bumped up against the structural member. This implies the gap between the structural member and the roller wheel, when the door is closed, is approx. 185 thou on the right side (and 0 on the left side). These values reverse around the midpoint of travel. It is suspected that because of this, and because there is a small observable gap between the door and the vault when it is fully close, the right and left side of the door are not parallel with respect to each other. In other words, adjusting the angle so that the starting gap is roughly 92.5 thou on each side should resolve the issue. Measurements to confirm parallel-ness between each side will be performed, and then an adjustment will be made to create even gaps between each side at the starting point. After this, a dial indicator will be set up again to confirm that, when opening the door, the gap is maintained throughout the duration of travel. Small deviations are acceptable, but in general what should be observed is a roughly constant gap, and no interference (i.e. if the gap begins at 92.5 thou, it should not drop to 0 or not exceed 185 thou, but should hover somewhere on the order of 20 to 140 thou, for example).
Edit [2023-11-24, 2]: a dial indicator was set up on the left side of the vault in a similar manner as described above. In this case, the indicator's reading remained roughly constant during the start of travel (starting with the door closed and opening it up), with only up to around 10-20 thou variation at first slowly, followed by a slow increase to up to approximately 135 thou. This is similar to the 185 thou observed on the other side. One suggested means of resolving the issue is: raise the entire door slightly with overhead crane, translate it sideways approximately half of door's lateral travel distance (i.e. around 90 thou) and then lowering it back down. This should, in theory, be acceptable. It may not resolve the issue of whether the door is rotated, but should give enough clearance on both sides throughout the entire range of motion to be deemed an acceptable fix. Other opinions will be gathered on the subject to determine if this could work. |
