LLO MC2 Violin Mode Q

Document #:

LIGO-T1200418-v1

Document type:

T - Technical notes

Abstract:

This is a writeup of a quick calculation to understand the measured violin mode Q of the MC2 suspension at LLO but is applicable to all HSTS. The interesting conclusion is that the violin mode Q is dominated by thermoelastic damping which has its peak nearby.
