|
Yesterday a leak was discovered in the ISAC-I experimental hall. The leak appears to be at the connection between the evaporator and the return water
line. 1 in of water was lost from TCS:TK1. The water is currently valved off to prevent further leakage.
A fault reportt has been submitted to mechanical |

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. |

|
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. |

A rotary limit switch was installed, attached to the shaft adjacent to the drive motor for the vertical drive system. This limit switch is not yet wired
to the control system and operational - this will be done at a future date and the e-log will be updated.

It was found that the conversion from voltage to vacuum (Torr) in EPICS is not correct for the XGS-600 controllers in use at the TCS. EPICS did
not correspond to local values displayed on the controller. An e-fault has been submitted. |
