OMC progress on Friday

[Jeff B, Jeff L, Rich A, Koji A]

On Friday, we looked at OMCS for the preparation of the installtion after the TF approval in the late afternoon.

- Dog clamps, 12pt screws, the cookie cutter, and its screws were prepared.

- The genie lift was moved near HAM6

- We looked at the cable routing. The quadrapus cables are too long & we have three unused connectors.
  They will be tacked on the OMCS structure.

- The isolation between the cable shields and the suspension structure was checked. We found that the
  shield of the OMC ISC cables are shorted to the suspension structure. The DCPD preamp housings
  (made of AL) are directly attached on the structure. (The situation is the same for the LLO OMC too.)

  We can't isolate the preamp right now unless we have some special PEEK components
  such as PEEK 1/4-20 screws or PEEK shoulder washers for 1/4-20. We have CLASS A, C&Bed Kapton
  sheets, which may be useful.

  On Monday morning, we continue to work on the cable routing while the remedy for the preamp isolation will also be explored.
