ECR for OMC Invar Shims

Document #:

LIGO-E1300288-v1

Document type:

E - Engineering documents

Abstract:

The D1102211 Diode Mounting Glass Blocks break when the screws are tightened to around 1 in*lb using the D1201466 PEEK Nut Plates as designed.
The proposed change is to bond D1300354 invar shims to the top of the glass blocks. The invar shims are threaded, thereby eliminating the clamping, and possible breaking, of the glass blocks.
