ECR: Add black glass panels to the OMC Suspension Assembly to mitigate stray light noise

Document #:
Document type:
E - Engineering documents
Other Versions:
Attach AR-coated black glass panels to the OMC suspension structure (and to the optics table beneath the OMC suspension) in order to surround and isolate the OMC from scattering paths to/from the vacuum enclosure and the reflective metallic surfaces of the optics table and the OMC.
Notes and Changes:
approved by Dennis Coyne to pursue detailed design and costing only. Once a reliable cost for AR coating has been established, then a decision will be made regarding if & how to pursue. An Operations CR may be needed.
