UC#46 was placed in pail# 301 in spot 1B and was 26.3mSv/hr when removed from the SHC. See attached PDF for vault 
details.

 The spent UC#47 was moved from the south hot cell to the spent target vault placed in pail #302 in spot 1C of the vault, it was 24.5mSv/hr when removed from the south hot cell. See attached for vault details.

Move went well no problems readings at East Target Station were very high at 500mSv/hr.

Ta#36 has been installed on TM4 and is awaiting leak and electrical check.

A small piece of the standard top insulator ITA3376 broke off during removal of Ta#35 (indicated with a blue circle on attached pictures).

"JP's connector, ITA2493 showed the usual and as yet undiagnosed "arc" mark (picture to follow).

The plastic retainers on the new torqtite gaskets showed rad damage.

See attached PDF for the details.

Ta36 was check by Maico and Chad.It was then carried into the anteroom.From the anteroom it was transferred into the south hot cell.

Tm4 w/ Ta#36 has been vacuum leak checked using the standard leak check procedure.

At 1:45pm RH was contacted to notify them that TM4 is ready to move.

TM#1 has been moved from the Conditioning Station to the South Hot Cell for the installation of Ta#37.

TM#1 has passed the the electrical check.

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.

 TM1 with UC#2 had the target installed, the heat shield line was pumped on and achieved a vacuum of 0.0 x 10^-4 Torr and a  leak rate of 0.0 x 10^-9 atm cc / sec with no response when sprayed with helium. An electrical check was completed by David and myself all values were withing tolerance.  The module was then moved from the south hot cell to the conditioning station where it will start pump down. The move was uneventful every operated as it should and there were no crashes minor or large. It was attempted to fill the containment box with argon prior to closing it but assuming that didn't work I estimate the target was exposed to air for a total of ~4 hours during installation and move. 

 On August 22nd TM1 was vented with Argon in the conditioning station. It had been pumping with just the roughing pump over the weekend so the UCx#2 target would not be exposed to oxygen. The move went without incident and took roughly an hour to complete. Once at the hot cell the panel was removed by Tom Lyth and a leak check completed with Bevan, David Wong, Grant Minor, and Tom Lyth present. The connections to source tray were checked starting at the top. Each connection was checked on either side of the VCR and at the center through the hole in the nut. For both connections on the source tray there was no response from the leak cart which was at a pressure of 0.0 x 10^-4 T and had a baseline leak rate of 0.0 x 10^-9 atm cc / sec. The leak check then proceeded to VCR connections on the Target. A leak was found on the upper VCR connection of the target and was repeatable. This leak was detected at the hole of the VCR nut connection by priming the line with helium and placing it next to the hole in the VCR connection. Response time was between 5 and 10 seconds to a maximum of 2.6 x 10^-8 atm cc / sec. The lower connection also appeared to have a small leak rate of 4.4 x 10^-9 atm cc/ sec but could be a result of helium drift. Unfortunately the target is not design to be repaired with manipulators and required the target to be removed from the south hot cell and repaired in the anteroom. The anteroom was prepared for the target by lining much of it with plastic so to prevent the spread of contamination. Once the target was in the anteroom it was leak checked again, the base pressure was 0.0 x 10^-4 and the base leak rate was 0.0 x 10^-9. A response from the upper connection again was detected in the 10^-8 range but no leak was found in the lower connection. It was attempted to tighten the joint to stop the leak but this caused it to increase to the 10^-7 range. This increase in leak rate is as expected from past experience because copper gaskets are used rather than silver plated ones. The heat shield cover was loosened and the gaskets from from both joints were replaced with the silver plated ones. The target was then leak check and passed with no response once again with a full pump down. The target was had an electrical checked with the megger and was within spec. The target was then placed in an argon bag and returned to the hot cell. The bag was damaged went placing it in the hot cell and there were not any acceptable options for leaving the target over night. The target was removed and and placed in 2 bags filled with argon for over night.

On August 23rd the target was removed from the argon bags that were still inflated and returned to the hot cell. The target was re-installed on the target module by Grant Minor, Tom Lyth, an Bevan Moss. One VCR gasket fell off during the first attempt and it appeared that the right target leg may have been slightly bent at some point. Other than that the installation went smoothly but slowly. The heat shield line was then leak checked once again by Grant, Tom, David, and Bevan and no response was detected from the source tray or target VCR connections, the base leak rate and pressure once again achieved the minimum detectable levels. The target module passed the electrical check with the megger, this test was completed by Bevan and Pierre Bricault. The module was then moved from the south hot cell to the conditioning station. Roughing was started at 3:00 and the turbo pumps were turned on at 3:45. The module was left to pump over night.     

Ta#36 was removed from target module 4.

The standard, unexplained, un-investegated, un-resolved "arc" were again present on "JP's connector", otherwise no apparent problems visible.

TM#4 moved from South Hot Cell to to North East Silo, move went well.

UCx#2 has been removed from Tm1 and put in a bucket with a slow argon feed and a lid placed lossely on top.

TaC#1 ITW has been installed and is awaiting testing at the cell.

TM#1 with TaC#1 installed passed the electrical test. With a value of 882MOhms that was meggered from the heat shield to the chassis, all other measurements are within spec.

TM#4 with SiC#26 HP has been checked electrically it has passed. It was noted that the Megger check of the Oven to Chassis (earth ground) and Oven to 60kV Common is low but will not hinder running, according to Don Jackson.  Also yesterday the transition piece that sits on the 55 pin connector was damaged from excessive handling, it was removed and repaired and it now back in place.

TM#4 with SiC#26 HP has been moved from the south hot cell to the conditioning station.

Base Pressure: 0.0x10-4

Stable Leak Rate: 0.0x10-9

Leak check of tube heater circuit, containment box side was performed.

Initail check at tube heater block on source tray yeilded a response 60 sec after the 2 second spray of helium. The response was very small and recovered immediately.

This area was checked twice more but the reponse could not be recreated.

Joint at the waterblocks was tested with an intial 2 sec spray. No response after 60 sec.

Waterblock joint was tested again with a 4 second spray. No response after 60 sec.

HP febiad target SiC#26 was installed onto Tm4 on Monday morning.

"JP's" connector required lossing of the two mounting fasteners. Connector was pushed tight to its mating half on the source tray and both fasteners retightened, and the mating checked; it was good.

Two new 7/8 long 3/8-16 fasteners were used for the febiad coil connections.

Installation went well.

Leak check was performed:

Base Pressure: 0.0x10-4

Stable leak rate 0.0x10-9

Left vcr joint was checked two times with a 2 second spray of helium with a 60 second waiting time between sprays; no response.

Right vcr joint was checked two times with a 2 second spray of helium with a 60 second waiting time between sprays; no response.

Fllod of system with a 6 second spray; no response.
