aLIGO bow-tie Pre-Modecleaner document

Document #:

LIGO-T0900616-v3

Document type:

T - Technical notes

Abstract:

This document was prepared in the design phase of the new Pre-Modecleaner (PMC) for Advanced LIGO. The current version is updated after building all aLIGO PMCs. A list of assumptions and calculations including the values for the simulation of the PMC can be found. Furthermore a prototype PMC was built and tested. The comparison with the design parameters shows that the properties of this prototype are in accordance with the parameters and tolerances that were calculated.
