HAM Seismic Isolation Requirements

LIGO-T060075-v1

Document type:

T - Technical notes

Abstract:

This page examines some considerations regarding the desired seismic isolation for the HAM optics platforms. For starters, we look at the effect of HAM platform motion on a triple suspension, specifically the mode cleaner (MC) triple (transfer functions for the recycling mirror triples are quite similar to the MC triple, so the analysis should apply fairly well to the RM triples as well).
