|
The sealing surfaces of the module side heat shield water block were polished on September 9th in the morning using Chad's polishing tool with
the following attachments:
- Scotchbrite pads (30 seconds) (after this step indium material from the previous seal was no longer visible on the sealing surface) |

|
Today Maico completed the new leak testing tool and blank off. He tested them with C-seals without springs and all was leak tight. He then inspected
the crushed seals and noticed that there was an area that was crushed less on both seals (more prominent in one, 20130906_tm3sourtrayefurb_P1020975)
and that this reduced crushed zone only appears on one side of the seal. This is similar to the failure seen on both sets of the heat shield lines. On |

|
Yesterday, Grant entered the Ante Room with David Wang to visually inspect the two sets of failed c-seals from the Heat Shield circuit, to remove the
second set from the Heat Shield water blocks, and to leak check the heat shield circuit with o-rings and a water-block-to-leak-detector fitting.
Some photos of the inspected seals are in the attached design review presentation. Some unusual marks were observed on both sets of failed |

Today Maico measured the thickness of three indium-plated inconel c-seals, presumably Ultra-Seal P/N 50606. These seals had NOT been in the Hot
Cell.

David Wang and myself lowered the leak testing cart into the Ante room and prepared the ante-room for the leak testing of TM3s line. David and
Grant then entered the anteroom and inspected the old c-seal and leak tested the the heat shield line. The line pumped down to the lower limits of the |

Today Chad entered the south hot cell on work permit 2013-08-29-3 to repair the leaking heat shield line. The heat shield line was removed from
the module and the surfaces cleaned. New C seals and spring were inserted and the line re-attached. During this time Chad also installed the new vacuum
gauge. Grant took video of this work and Keith some pictures. The video and pictures can be found on the M: drive (groups) in the RH folder. The total |

The heat shield circuit was pressurized with air (15-20 psi) and snoop applied to the water block joint and brazes. Bubbles formed at the joint between
the two water blocks indicating that the leak is a c seal problem. Pictures attached but also on docushare Collection-11285. |
