Electrical check done on TM#2 around the 25th of June 2015, this was before the coil line leak was found.

The leaking 1/8 NPT(M)-1/4NPT(F) adapter on the ITW dump circuit is replaced.

Target pit Hepa filter has been replaced today. There is 500 counts on swipe which is taken inside of the replaced filter. The field measurement on the filter wood box  is less than 0.5 usv/hr on contact. Right now,The outlets of the old filter are sealed with thick plastic and duct tape. The whole filter is wrapped with plastic sheet and tape. It has been moved to SHC ante room.  It will be moved out of there by Tony.N soon with RPG help.

TM#2 has failed the electrical check see attached pdf for details.

A few additional higher-resolution photos of the TM2 source tray with new spacer ITA6270, and bent copper ground line clip.

Also attached is a photo of a 3/8" copper line placed in between the loose ECR line and the Mounting Support Plate line, for dimensional reference.

Ultem high voltage spacer installed and 9 pin banana plug plugged in. Target has been inserted into the hot cell and will be installed after base-line electrical checks...probably first thing in the morning.

Gas lines extensions installed yesterday were too long and gas lines touched top inside of containment box. They have been removed and the gas lines re-installed in their original manner. Gas lines have been "adjusted" as to clear the tube heater lines, which was the original issue.

IMG gauge, clip for ground to window lines and gas line extensions were installed today.

David and I also tried to locate the short between the coil line and MSP/Heat Shield...it went away for a bit...but is back.

Update the TH schedule according to present TM2 refurbishment process. See attachments 1,2

2015-07-20 , Update the TH schedule after some changes on TM2 and TM4 arrangement. See attachments 3,4

Chad and I leak checked the coil 1 circuit(R,U) after rebuilt coil line is installed on TM2 source tray. The pumping down on the circuit is very quick and smooth. The LD base lake rate 0.0xE-9 atm.cc/sec. Base pressure0.0xE-4 torr.

Chad sprayed lots helium on the R( coil 1+)and U(coil 1 -) water blocks. During  1 minute waiting time, there is no any response on LD. The R and U water blocks and C-seals are leak tight.

TM2 coil line R,U has been vacuum leaked check at the hot cell and has passed with no response from the leak detector.

water block jig installed, module side sealing surfaces re-polished and cleaned. Coil line inserted into the hot cell and installed onto the module. Bolts torqued to 90 in.lbs. Received .13mSv.

Containment box was removed from Tm2 this morning  in preparation for installation of coil line and all the trimmings.

TM#2, no target, has been moved from the north east silo to the south hot cell.

TM#1 has been moved back to the south west silo from the conditioning station.

 The roughing pump was replaced with a more leak tight pump due to the discovery of Rn-220 migration while roughing on TM1 in TCS

Coil line has been in RPG's ultrasonic decon over night. Initial swipes this morning picked up 5000 counts. It has been decontaminated to the point no more contamination is being found and nothing can be found with the frisker...so...it's ready for Maico and Dan?

TM1 and CS  vacuum system are connected. All turbo-pumps are started. The new TP1S works fine also. The pumping down looks good so far. During the TM1 and CS roughing down time, Joe .M noticed a Rn-220 level surge up in TH . Then,the Rn220  level slowly dropped back. Anders suspected this Rn-220 surging is related to the TM1 roughing down at CS. We decided we will stop the pumps , vent the CS , and roughing  again tomorrow. During the same time Joe will monitor  Rn-220 level in TH to see if the surging is repeatable. We want to learn more on this TH Rn-220 issue.

coil line has been removed from the hot cell. Initial decon was performed...after it still appears to have approximately 200 counts. It will now be transfered to the rad waste decon facility for further decon.
