Optimization of thermal noise in multi-loop pendulum suspensions for use in interferometric gravitational-wave detectors
Abstract
Description
We study the thermal-noise spectrum of multi-loop pendulum suspensions for test masses in interferometric gravitational-wave detectors. The dependence of the thermal noise on suspension parameters and on properties of the wire material is discussed for the situation in which the losses are dominated by the internal friction in the pendulum wires.
