ITE:ANODE supply reading strange currents - 17mA with the power supply on and no voltage. Checked anode circuit from electrical room:

Anode wire in electrical room shows 0L at 250V

Circuit with 50kOhm resistor mostly looks good (49-52kOhms) but a couple times read 28kOhms, no idea why. Tried jiggling all cables, unplugging and replugging and everything looks fine.

But power supply still seems to be giving out signal for 17mA readback. Decided fastest to swap with TCS power supply and troubleshoot this one on the bench.

The motor cable for the storage vault was replaced as the old one was showing signs of wear. The U-track that the old cable ran through was also bent as a result of being hit.

In the process of replacing the cable, an e-chain was installed for cable management purposes. Mounting brackets were modified and a new U-track was installed as well. The new hardware is more robust than what was previously installed.

The vault door was opened and closed multiple times while observing the e-chain - everything behaved as expected. The system is operational.

Solidworks model IRH0189 is updated to show the changes

 The spent target UC#38 was packed into pail #274 and placed in spot 1A of the vault. It was 33.3mSv/hr when removed from the north hot cell. See attached PDF for more vault details.

On 26/Sept/2022

Chad disassembled the right operator side manipulator, and noticed that gears in the handle were quite tight especially when compared to the left operator side manipulator. 

Once a dry grease was added, and the handle reassembled all seemed to be in working order.

There was noticeable wear on a shaft and Chad has suggested to order some spare parts for the wrist and handle. 

Myself and Maico were able to top up the NHC window oil.

The oil was filled through the expansion tank

- the Nitrogen line closed and the Nitrogen pressure valve was disconnected to ensure that no oil would go in to them.

- the pressure relief valve was disconnected to act as an air bleed line while we filled the oil

- with a funnel we slowly added the oil until the oil level could be read, showing about half full

- about 1.5 liters of oil were added

- once filled the Nitrogen line was reattached and the pressure was returned to recommended level 

- the remaining oil was returned the RH shop

Now the oil level will be monitored, which will help identify if there is any leak in the system.

A fully built steerer sub assembly ITA2826 revision E was boxed and sealed and put on rack storage in ISAC B2 South Hot Cell area. It is contained in a blue bin and green tag. 

It is advised if this assembly is used, it should be inspected for damage before using in a source tray.

A modification was made to integrate the hot cell's lift table into the E-stop circuit. See work permit I2022-10-07-1

The E-stop mounted on the right side of the small enclosure adjacent to the operator station will now serve to stop the lift table's up and down motion, as well as the turntables up/down and CW/CCW motions. Functionality was checked by B. Webster (electrical services) and A. Newsome.

Note: it is recommended next time there is a hot cell entry to inspect whether or not the limit switch specified in the schematic is actually installed. The schematic should be updated to match the drawing.

Redlined electrical drawing photo attached to this e-log, and the paper drawing is left inside the lift table's control box. The schematic will be revised based on the redline updates, likes as part of work request #6342 (to integrate this drawing into the turntable controls drawing package).

 Spent target move done. The SiC#44 was moved from the north hot cell to the spent target vault. It was placed in pail#275 and placed in spot#4A. It was 42.6mSv/hr when removed from the north hot cell. See attached PDF for further details about the vault.

Please note we will only have two free spots in the vault at the start of the running period after the winter shutdown 2023.

During the last ITE run with the SiC#44 target, the ITE:TBHT controls card was fried twice. The first time we put in our spare, and the second time we just continued to run without controls readback. For the C#4 run starting Oct. 19, we used the conditioning station supply. As soon as one of the other supplies is fixed, we will install it in the conditioning station. The equipment list (https://triumfoffice365-my.sharepoint.com/:x:/g/personal/cbabcock_triumf_ca/EQPffP4p1P9JqEDWIHGRPfsBVDSQjMCv-M8ZNg4ngkyGHw?e=fnLVYe) tracks these movements.

 The spent UC#39 target (pail #276) was removed from the north hot cell and place in the spent target vault (spot 4B) it was 14.4 mSv/hr when removed from the north hot cell. See attached PDF for further details. 

Did the PIE on UCx#39-IGLIS on Thursday Nov. 2 2022, couple pictures uploaded to docushare. Did not remove the target, just the heat shield cover.

Final electrical check on the module showed a dead short from TGHT/TBHT to HV common, which we did not see online. Seems like it must have occurred after ramp down? It persisted on the target after we removed it from the module. We couldn't find any obvious contact points, because it seems it did not happen while current was running in the target. Possible locations are the bottom support leg for the TBHT and the top of the right side target leg, though it was difficult to confirm with the camera.

Otherwise the only thing to note was a blacker-than-usual spot on the inside of the Cu heat shield, downstream in the proton direction.

The following five pails were moved to the mini-storage vault today under work permit I2022-12-16-1:

• #239 (formerly vault location 7A): 1.38 mSv/h @ 1m
• #245 (formerly vault location 6B): 1.56 mSv/h @ 1m
• #264 (formerly vault location 6A): 748 uSv/h @ 1 m
• #267 (formerly vault location 1C): 708 uSv/h @ 1 m
• #268 (vault location 7C): 809 uSv/h @ 1 m

The mini-storage vault is now full and ready for transfer to F-308 flasks.

The following measurements were made on other pails:

• #211 (vault location 3C): 4.21 mSv @ 1 m
• #217 (vault location 3A): 1.05 mSv/h @ 1 m
• #246 (vault location 6C): 1.98 mSv/h @ 1m
• #274 (vault location 1A): 4.78 mSv/h @ 1 m
• #228 (vault location 1B): 3.86 mSv/h @ 1 m
• #256 (vault location formerly 7A, now 7B): 3.60 mSv/h @ 1 m
• #260 (vault location 5B): 1.46 mSv/h @ 1 m

The target index spreadsheet has been updated to reflect these changes. See attached PDF print.

[edit 2023-01-03] The crane was powered back on this morning - there do not appear to be any faults and it seems that the crane was unaffected by the power outage.

The ISAC target hall overhead crane was powered off for the holidays. Note that this may result in the commonly observed PLC battery failure issue when the crane is powered back on in the new year.

The following three pails were moved from the main storage vault to the mini-storage vault:

1. #211, Ta#58 (formerly vault location 3C)
2. #217, ZrC#8 (formerly vault location 3A)
3. #228, UC#37 (formerly vault location 1B)

The target index spreadsheet has been updated.

 UC#40 was moved from the north hot cell to the spent target vault. It was placed in pail #278 put in spot 1B and was 15.6 mSv/hr when removed from the north hot cell.

Also Ta#62 in pail #256 was moved from spot 7B back to 7A where it was originally located. This pail in the future will have to be repacked due to the fact it lacks a reinforcing disc in the bottom of the pail.
