|
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 |

|
Optics tray has been removed from module.
Waterblock jig installation has commenced. Of note, jig installation on TM3 has proven more dificult than the previous installation on TM2. Many
of the waterblock assemblies are skewed (not perpendicular to plane that they should be...perpendicular to). |

Friday, April 26, 2013, 11:20, chad fisher, South Hot-Cell, Repair, TM3, , Water Block Jig (back half)
|
The back half of the water block jig (services tray side) has been sucessfully located onto the module.
About 50% of the waterblocks have centered themselfs it their respective cups and the rest look good for concentricity but will require some gentle
wiggling to get them to seat. |

Tuesday, April 30, 2013, 07:51, chad fisher, South Hot-Cell, Repair, TM3, , Coil line flow check
|
David and I checked circuits p and q (the water cooled coil ciruit) for flow this morning as, with the source tray still in the module, there was both
a leak and a leak tight blockage. Both p and q allowed air flow through them confirming that the blockage was in the surce tray side of the system.
The heat shield circuit was also tested for flow and it passed. |

|
David and I preformed a helium leak check on the service tray waterblocks and verify that no damage had been done during jig installation. All 14 circuits
were checked and verified to be ok except circuit E and circuit I which were unstable when helium was applied. The resonse time on E and I would suggest
that it is an issue with the bungs that were used and not the braze joint however. |
