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). |

|
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. |

Service tray side of the waterblock jig is installed and all locking tabs enagaed save the heat shield circuit. Locking tab for heat shield circuit with
be worked on Monday morning and installation of the source tray side of the waterblock jig should commence on monday as well. |

|
Chad removed the source tray from TM3 today, see attached picture (video was also taken). There was some interference between the window cooling
lines and the frame work as well as the clamps for the ground electrode and the water block alignment jig. There was also interference between the optics
alignment post (specifically the mushroom top) and the water block alignment jig. Investigation into these inferences needs to be completed as they could |

The source tray has sucessfully been removed from TM3.
I will put a report in the TM3 rev 3 docushare directory as there were some items of note during this procedure. |

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. |

With the aid of nic new manipulator snap fingers made by Maico the peek cable ties restraining the 9 pin connector wiring to the gas lines have been
cut. |

|
Travis and I removed the 55 pin connector from the service cap today. The feed through was left in place as a new design for the replacement has yet
to be designed. It was not possible to test if the cables could be pulled easily as I believe there is still 1 cable tie in the containment box. The wires
were cut flush with the top of the copper tube in case Chad cannot remove them via the hot cell. Other items removed include several cable ties and a clamp |

|
Testing on TM3 without a source tray was completed on 13/05.2013. All items were tied to common and the water blocks were left open at the bottom
of the module. They were left with the quick connections at the top. The vacuum was in the low 10^-6T range so this was deemed acceptable. The cooling
lines withing the cage in the target hall were shorted so flow could continue. As you will see from the results a maximum of 44kV was achieved before a |
