TM3 old source tray, old target hall high active water resin tank, and  old 2A window RH clamp are transferred from TH to cyclotron lower vault basement 10 and 10A location for storage. They are placed beside and in front of old TM1 and TM2 source tray boxes which stored there in 2018. 

Edi and I inspected roughing pump ITM MP1, primary backup pump ITHMP1, and secondary backup pump ITHMP2. We checked oil level and color on all pumps.  Refilled lubricant to ITMMP1. ITHMP1 and MP2 oil level is fine. ITH MP1 oil color is darker than MP2. But, both them are ok still. Shielding block has been restored after the job.

Travis assembled and tested the steerer wires March 31st (see attached)

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.

Five of used  internal leaked  TP BVs are serviced and repaired. Internal plunge  o-ring and case o-ring are replaced on all five BVs. Leak checked valves after  . They are ok to be used as spare parts.  The are active parts stored in TH now.

The spent target assaying turntable was repaired. It was tested today with a load exceeding the maximum it would need to handle during rotation (100 kg). It works as expected and is ready for operation.

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:

1. 06
2. 13
3. 15
4. 16
5. 19
6. 20
7. 21
8. 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.

Alignment notes attached for the optics tray for the refurbished tm3 with the new service and source tray.

*Note: Drive screw bracket sheared off during alignment check with source tray. The drive bracket was replaced. The optics tray was re checked. The front element was .015 to left and centered u/d. The rear element remained the same. The center element could not be checked to do the assembly.

 Shielding blocks have been moved from ITE to ITW and MAA is secured.

 5 Shielding Blocks have been transferred from ITW to ITE. MAA is secured after moving.

 Five shielding blocks are moved from ITE to storage area ( one of them is sitting on B2 as limit of room) for target stations maintenance in 2025 winter shut down .
