TM4 with UCx#37 was connected in ITE. Attachment available.

UCx#30 has been installed onto TM4 with new high current fasteners torqued to 130 in lbs.

UCx#3 was packaged into a spent can, double bagged and the bag and cans filled with argon as much as possible. Lid was attached and can moved to the storage vault. The target was placed in in Pail 93, and placed into slot 1C of the vault, it was 11.7mSv/hr when removed from the south hot cell. See attached file for latest vault details

UCx#3 has been installed on TM1.

Leak check also complete.

Base Leak Rate 0.0 x 10-9

Pressure 0.0x10-4

Two checks on upper heat shield joint - no response (2 sec spray/check)

Two checks on lower heat shield joint - no response(2 sec spray /check)

10 sec flood of all heat shield joints - no response

Electrical check coomplete.

An autopsy was performed on UCx#3 yesterday afternoon. This autopsy followed the plan written by Anders. Indeed, both sides of the target oven had seperated from the central block.Pictures were taken by Anders and Pierre.

After the disection the target was placed back in a can under argon. Any small piece were placed in a zip lock bag and also put in the can under argon.

UCx#29 has been removed from TM$ and placed in a pail backfilled with argon until it can be moved to the storage vault.

UCx#28 has been removed from TM4. Guard screws on 5(10) pin connector had to be removed to get the connector to un-seat properly for removal.

Dummy Ta target has been removed from TM4 and UCx#27 installed

UCx#19 has been installed onto TM4. High current fasteners torqued to 130 in lbs. Has been leak and electrical checked and is ready to leave hot cell.

On Thursday, January 26th UCx#18 and Ta#50 were inspected and packaged into spent target pails, move to storage vault.

UCx#14 has been removed from TM4 and Ta#47 installed. No marks on 9 pin connector on UCx#14.

UCx#14 installed onto TM4. High current fasteners torqued to 130 in lbs.

UCx 29 TM4 post run electrical check is done before target is removed. Everything is normal on measurements.

TM4 HS Leak check result is good . No leak. electrical check after target installation: Bias to chassis 550 Mohm. Coils are shorted each other and shorted to 60 KV bias. ABCD to 60KV bias 500V Megga measurement are 100M at least which is good. EE to bias are OL at 500V. The electrical check result is good.

UCx 32# P2N target in vault slot 1B is repacked is morning for Ferran to take out his samples( in two small plastic containers) stored in pail last July when Chad did the spent target job. The job went well.  Old pail # is 254# and new pail # is 233. It is put back to 1B in vault.

UCx #2 has been installed onto TM1.

Installation went well except the left leg got bent slightly sometime between testing on the jig and installation onto the module (probably during removal for the argon filled bag). Leg was gentle offered into place and its clearance with the heat shield double checked with both a mirror and goose neck camera. Leg was close to ther heat shield but appeared to have clearance. Anders and John Wong viewed this and deemed it ok. Video images of this clearance were recorded.

Leak checking was also completed successfully:

Base pressure on the leak detector was a constant 0.0 x 10-4, Stable leak rate was an unwavering 0.0 x 10-9.

Both heat sheild circuits were checked twice (starting with the highest gland) and sprayed with a 2 second burst of helium into the test hole in the nut. No reponses were seen after 1 minute an any of the circuits.

Bevan Moss and David Wang performed an electrical check which they relayed to me that the module with target installed had passed.

On Tuesday, January 24th UCx#18 was removed from TM2 and Ta febiad dummy installed. I encountered the same issue mounting the new target as last time. Was able to determine that the issue is the routing of the waterlines to the right-hand (as viewed from the operator) high current tube heater. The lines interfer the the target mounting plate (bottom right hand corner).
