Arm Cavity Baffle Edge Scatter

Document #:

LIGO-T1100056-v2

Document type:

T - Technical notes

Abstract:

The scatter from the exposed frontal edges of the Arm Cavity Baffle is calculated. It depends upon the BRDF characteristics of the baffle material at small angles, upon the vertical tilt angle of the baffle edge, and upon the radius of the edge.
