Electrical check done on TM#4 with UC#19. See attached PDF for results.

TM#4 has been moved from the conditioning station to the south hot cell.

Did the start of the running year electrical checks of both TM#2 and TM#4 with no target attached to either module. TM#2 was in the south hot cell and TM#4 is in the conditioning station under vacuum.

Rust on S/W silo and cover plate stored at silo area are cleaned up.

ITE clean up is done.  HV cage inside is wiped.

2A window has been removed from the vault and moved over the cyclotron vault tunnels.  Attached is the updated storage vault list.

The 2A3 window now has a lid, and lift yolk on it and it has been installed in the spent target vault in spot 2A. The lid is a normal unmodified and has no sealant on it.

The pail containing window was transferred from the Storage Vault to the Cyclotron Vault Tunnel Storage 2017 Mar 24. It was placed in a brick bunker along the north wall and marked with item #1434. RPG storage form is attached.

Highest field measured at 0.5 m was 3000 uSv/h with an estimate of 4000 uSv/h on contact with the pail. Pail exterior was not contaminated. See attached storage form for details.

 

Transfered the 2A window from the ISAC Storage Vault to the Cyclotron Vault Tunnel Storage area. RPG storage form attached.

TM4 service cap rust are cleaned out at TCS. All top surface of TM4 are wiped and cleaned . The module looks good now. see attachments

Strange noise and a burning brake type smell was observed yesterday by David and Anders when running the main 20 ton hoist locally.  A service call was arranged today with Gordon Crane.  No major issues were found.  A more detailed summary is in the attached e-mail correspondence.  Gordon Crane will issue a formal report, but they recommend replacing both sets of brake disks and brake calipers. - Grant

Electrical check of the Ta test target on TM#2

TM#2 has been moved from the east target station to the south hot cell.

Yasmine and I did a rust inpsection on TM4 service cap inide surface and shielding plug surface. No rust has been found. Also, all steel bolts on this surface look fine. The inside of silo held this module are rust free as well.  See attachments

TM#4 has been moved from the SW Silo to the conditioning station.

All target in the ISAC spent target vault have been either assayed or had their fields measured or both.

The west 'Z' motion cable on the east manipulator has successfully been replaced. The job took slightly less than an hour (including inspection of the scissor table hoses) and I received 0.075mSv. Scissor table hoses appear to be fine and also didn't "shed" or flake at all when checked by hand.

I watched rust on TM4 and its silo. Most of rust are on est side of module and silo. See attachments

I have moved the suspected "hot" items in the hot cell and placed them under some lead bricks. I have re-measured the fields and it has been reducded to 90 uSv\h at the manipulator repair area and 110 uSv/h at the previous 1.82 mSv\h area.

Did a dry run with the latest procedure with Dan Mcdonald. Elapsed time was approximately 30 min.

I have re-measured the fields in the hot cell. Fields at shield door Al cover are 101 uSv\h, in cell at the east manipulator are 245 uSv\h, and the largest field is 1.84 mSv\h...this appears to be the high current fasteners removed from the last target.
