Leak detector is connected to ITW TP4. LD Base leak rate 0.0XE-09 atm.cc/sec. Helium line is connected to existing window leak check 1/8 " copper tube. Applied 18psi helium for 1 minute. No response on LD. The window seal is good on ITW vacuum vessel. 

 The west entrance module has been moved from the silo to the west target station.

Tank level down from 76 to 55 in on TK1

Valve replaced by Curtis today

 SiC#37 has been moved from the South Hot Cell to the Spent Target Vault. It was placed in Pail #165 and put in spot 3B of the vault and it measured 25.8mSv/hr upon removal from the hot cell. See the attached PDF for details

 A Motorla CP200 portable two-way radio was tested today for use inside the ISAC hot cells.  A High Technology Communications Throat microphone PRO model from Planet Headset was used with the radio.  Chad entered the NHC wearing the throat mic and radio under a air supplied hood to mimic real world conditions.  Communication was clear with the other person in the NHC service area, in the SHC service area, at various locations on the B1 level, and even with an operator in the TRIUMF Main Control Room.

This testing satisfies RS 104 of the NHC requirements specification (Document-131915, Release 1)

Field measurements have been taken to determine the level before entry for repair of manipulators.

Field on contact at manipulator is 560 uSv/h, and at approximately 1/2 meter at table surface 920 uSv\h.

The shield door has been opened and fields measured at 77 uSv/h on contact at the AL. panel.

Shorted TGHT with new high current connector assembly and heated to 600 A. Temperature measured on half way point on cable ~ 70 deg C and on connector ~60 deg C at 600 A, 45 / 40 deg C at 400 A. Target Hall locked out during test

hot items have been moved and shielded as much as possible. Field at left manipulator has been reduced from 560 uSv/h to 85 uSv/h.

Tuesday, June 26 the broken tong cable was replaced on the west manipulator in the south hot cell. Wednesday the tong cable was preemptively replaced on the east manipulator of the south hot cell.

At the end of manipulator repair Thursday the ventilation pre-filter in the hot cell was changed. Old filter remains in the hot cell until such time as it can be removed.

Annual ITW water signals interlock check are done. Everything works good.

Installation of the diagnostic connections between the NHC hot and cold sides has been completed.  The cable bundle was prepared by Travis Cave in the electronics workshop with connectors attached at one end only.  Metal fish tape was first ran through the conduit from the cold side to hot side, the non-terminated end of the cable bundle was attached to the fish tape inside the cell, cable pulling lubricant was applied, then the cable bundle was pulled through the conduit to the cold side, and the cold side terminations were then made.  For future replacement of the cables and connectors the same method should be used, and a minimum of 6m of cable length.  Connector details can be found on drawings IRH1765 (hot side) and IRH1767 (cold side).  Conduit is 1" trade size PVC type (PO#3041531).

 Yesterday the spent UC#22 target was moved from the south hot cell to the spent target vault. It was placed in pail #167 and placed in spot 4A see attached PDF for details.

 On July 30th the NHC diagnostic signals were tested:

- 9 pin CPC: a shorting plug was installed on the hot side - continuity check results were as expected

- 4 pin CPCs:  snake camera installed in both hot side connectors with portable monitor on cold side - both connectors worked as expected

- USB: laptop connected on hot side, USB mouse connected on cold side - worked as expected

- Ethernet: laptop connected on hot side, cold side connected to building ethernet port - connection to network worked as expected

- SHV: a shunt was installed on the hot side - a short circuit was measured from the cold side as expected
            with no shunt installed the line was Megger tested: 1.63 G-ohms recorded @ 1000V

The control panel switches for the in-cell receptacles were also tested.  Each switch (a - d) worked as expected.

On July 31st the gas supply solenoid valves were tested.  60psi air was hooked to each solenoid inlet.  With the valve closed there was no air flow.  When each push-button or switch was activated air flow was observed through the correct solenoid.

I did a helium pressure test on TM2 HS line at TCS. At 70psi helium, the leak rate is 2.5 xE-7 atm.cc/sec. I think this is the number that close to result before which is 1.7xE-9 atm.cc/sec. WE know there is a small leak on this water block seal. Chad  and I did helium  spray check yesterday at SHC. It was good at bottom scale.  No much worry on this low E-7 range leak.

 The spent Nb#8 target was moved from the south hot cell to the spent target vault. It was placed in pail #168 and place in spot 2A in the vault. See the attached pdf for vault details.

 The west entrance module has been moved from the west target station to the south hot cell, for a bellows replacement.

 Ta#56 has been moved from the south hot cell to the storage vault. It was placed in pail#169 and place in slot 2C of the vault. Also the vault is now full with 24 spent targets and can no longer accept any new targets. See the attached PDF for further details.

 Targets SiC#34 , Ta#45,46,47,50 have been moved from the spent target vault to the mini vault.
