摘要: Pendulum suspensions for laser interferometer gravitational wave detectors need to have an extremely high Q factor minimize Brownian motion noise. In this paper we analyze the limits of compound pendulum. We show that observed acoustic loss niobium can allow pendulum factors 1010 be achieved. This should enable a 3 km terrestrial detector achieve strain sensitivity 10−22/√Hz at frequencies as low 10 Hz. At cryogenic temperatures up 1012 achievable.
