Friday, March 01, 2019, 09:57, chad fisher, South Hot-Cell, Repair, TM2, , TM2 Source tray removal
|
TM4 optics tray was installed onto the old TM2 source tray yesterday and tray filled with non-active metal scrap. Tray inserted into transfer frame 95%
yesterday. During insertion the ball nut of the transfer jig became unfastened from its drive plate. This will have to be fixed before the jig can be used
reliably again however we were able to finish the job...the transfer jig is 20 years old now so it is not entirely suprising that it needs some attention. |

|
Spark between HV cover vertical mesh plate and HS 60KV bias connecting clamp 90degree angle at 55 KV on TM2 top. HV cover is removed to test above
55KV. The spark triggered TH and SHC ventilation secondary alarm. |

|
Polishing of the water block sealing surfaces has commenced. First attempt was on block B with low nap brown polishing pad (the least aggressive pad
prepared) and isopropyl for 30 seconds. This cleaned a little but did not remove the "ring" which I believe is water scale. I will step up to
2000 grit wet sand paper and iso next. |

|
After trials with 2000 grid wet paper I have moved up to "red" scotch brite. This seems to have worked the best so far although it took two
minutes to remove the ring that the other materials could not remove (see picture).
I have moved to next circuit. Currently at 3 minutes and 30 seconds with scotch brite but significant ring remains. |

|
Stage 1 polishing (water scale and at least 99% of visual indium removed) has been achieved on all 2 seal water blocks that will be used (Ground electrode
has not been polished). Process required 3-4 3minute cycles of the tool using scotch brite pads with the tool running at approximately 75 psi. |

|
Stage 1 polish has been achieved on all single seal water blocks using the single pad tool run at 75 psi, 2 3 minute cycles per block using red scotch
brite. |

|
Phase 2 (intermediate) and Phase 3 (Final) polishing is complete on all water blocks on TM2 (minus ground electrode circuit which has only had a cursory
cleaning). Phase 2 with 2000 grit wet sand paper and isopropynol for 1 minute with tool at 75 psi, Phase 3 with Veltex polishing cloth for 1 minute with
tool at 75 psi. |

|
New seals with a blank off cap are installed on TM2 window line water block. The seals are checked at TCS with 70 psi helium for 5 minutes
with LD at 0.0xE-9atm/cc.sec. No response on LD during test. Seals are good. |

|
This morning new water block fasteners and gas line capture nut fasteners were inserted into the hot cell. Window waterline blank off was removed from
TM2, surfaces inspected and given a polish with Veltex (30 seconds, 70 psi) as there was a small bit of c seal residue. Transfer try with new source tray
has been latched to the module. |
