Friday, July 10, 2015, 14:15: Roughing with new pump

TM#2 has been moved from the south hot to the north east silo. TM#1 has been moved from the south west silo to the conditioning station.

Water block jig has been removed. Stuck source tray side water block jig component has been removed. An attempt was made to connect the gas lines to there bracket however they contact/interfer with the tube heater lines...Anders is looking into a solution.

Containment box and front cover have been replaced and TM2 is ready to move to the silo.

July-06, 2015. Chad , Grant and I did the bubble test on R,U water blocks. We suspected the leak on the R,U circuit is from C seals on the water blocks so we did this test first. I applied both air and helium to R,U circuit , Chad applied snoop soap on the R,U water blocks.The air and helium pressure was increased from 40 psi to 90 psi Max step by step.Chad did not see any bubbles on the water blocks during the test. Since we did not find the leak source, we decided to do vacuum helium check on the all joints and c-seals of the R,U lines later.  Finally, We found the leak by vacuum helium spray the day after this bubble test. See other e-log.

Chad and I leak checked coil line(R,U) on TM2 at SHC yesterday. The leak detector was pumped down to 0.0Xe-9 atm.cc/sec before the check. Chad sprayed helium on the soldering joints connecting the cooling copper lines to the small holding blocks for the coil terminal(R,U).  After sprayed helium 2 seconds, I saw the leak rate on LD started to climbed up. The highest leak rate is 4.0xE-8 atm.cc/sec. It is a very positive response. We waited the leak detector pumped back to 0.0xE-9am.cc/sec, and tested again on the same joints. The result is same. Chad also sprayed helium on the R,U water blocks to check the C-seal. I saw a delayed tiny response on LD ( from 0.0 to 1.3xE-9atm.cc/sec). We think this tiny response is caused by the helium drifting to the leak soldering joint, but not a real C seal leak.

R U coil line removal started at 11:30. Water block jig installed and coil line disconnected from module.

CS TP1S had been replaced with a new TP-301 pump this morning.The old pump was broken last week.

• The archiver is now merged with ISAC - data available under Utilities - Archiver Retrieval
• Old archiver data is available under Utilities -> Archiver Retrieval - old
• Strip tool save/load and export files under /data/tcsdata
• Login via isacepics1.triumf.ca. TCS button on ISAC menu

Field measured at block "R" through tool port with pole monitor is 6.65 mSv/H.

There are three air hoods and two air lines currently available.

First thing this morning the hot cell was "cleaned up" in preparation for the return of TM2 for attempted verification and locating of leak on R/U coil circuit.

Containment box has been removed and front cover reinstalled to provide some modicum of shielding form the entrance and exit windows. Box was placed at an angle in the corner to try and minimize line-of-sight with potential worker(s).

Did notice some funny discoloration of both sides of coil water block "R" as seen in attached picture.

Updated the schedule before the weekend 2015-07-03. See attachment 1,2

Updated the schedule according to present TM2 refurbishment process. See attachment 3,4

 Some reboots will be done.

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

UC#12 has been moved from the south hot cell and placed into storage. It is in pail #125 and in spot 1C of the vault it had a reading of 25.1mSv/hr upon removal from the south hot cell. See PDF for vault details.

TM#1 has been moved from the south hot cell to the south west silo.

 See e-fault 8233. Edi assisted in diagnosing the problem. The pump will have to be replaced.

 I leak checked TM2 at CS this afternoon which including air to vacuum check on service cap and helium pressure test on water lines. There is a small leak on water line R ,U (COIL1) during the helium pressure test.. Below 20 psi helium, there is no leak on it. But , once the helium pressure is increased over 20 psi, it showed up on Leak Detector. At 60 psi helium, the leak rate is 9.4xE-9 atm.cc/sec. For detail information, See attachment.  All other water lines and air to vacuum seals are good.

TM1 was disconnected in ITW  this morning. The ITW was vented with argon last night.

UCx#12 has been removed from TM1 and placed in a pail with argon.

Right leg (B) of target is clearly broken.

Containment Box cover re-installed and module ready to move.

TM#1 with UC#12 has been moved from the west station to the south hot cell.
