I have inserted the test target for TM4 and the CS into the hot cell.
I had some concerns about the condition of the target which I have discussed with Pierre and he has cleared. Pictures are attached. |

Chad and i did a leak check on TM4 heat shield circuit with installed dummy target at SHC today. The leak detector is pumped to 0.0xE-9atm.cc/sec.Chad
sprayed helium twice on each VCR joints .There is no any response had been found on the leak detector during each 45 seconds waiting time. The TM4
heat shield circuit with dummy target is leak tight so far. |

|
On Monday, March 11 the containment box was removed from TM4 and a vacuum leak check preformed in an attempt to locate the leak in the ground electrode
circuit.
Following Pierre's work plain helium was sprayed was the highest joint accessible towards the lowest. |

Further attempts to localize the leak were unsucessful. The circuit was pressurized with 60 psi air and snoop solution was applied to both the braze
joints and the mating surface between the two halfs of the water blocks. Unfortunately, no visible bubbles could be dectected.
This was reported to Grant and Pierre and it was decided to continue with removing one of the vcr gaskets from the optics cooling lines (on the |

The containment box has been re-installed and the window waterlines reconnected and leak checked.
The window lines did pass the leak check, however the leak dectoctor did not pump down past 5.8 x 10-9.
The front cover has also been reinstalled. |

Thursday, March 14, 2013, 07:18, David Wang, South Hot-Cell, Standard Operation, TM4, , TM4 window cooling line leak check
|
It took a long time(more than 1 hour) to pump down the TM4 window cooling line during leak check time. The base leak rate could only be
pumped to 5.8xE-9 atm.cc/sec.Base pressure is 0.0xE-4 torr which is bottom reading. Chad and i did the leak check at this base leak rate .No leak had been
found. The window cooling line is leak tight at this stage. A pressure helium test will be fulfilled in conditioning station on this cooling line later. |

Electrical check of TM#4 SiC#28 (RFQ Target) has been completed. It passed the standard electrical checks for the target part, but the electrical check
for the RFQ part is suspect, see the attached PDF for the details. |

|
Chad and I did the TM4 heat shield leak check yesterday at SHC. The leak detector was pumped to 4.6 xE-9atm.cc/sec, and 0.0xE-4 torr after 1.5 hours
pumping. Chad sprayed helium twice on both VCR fittings. There is no response had been found during each 45 seconds waiting time. Since the module moved
to ITE directly,we didnt have helium pressure test this time. I would say thee heat shield circuit is leak tight. so far. |
