Abstract

A modelling code has been developed that allows the thermal noise in a pendulum suspended by multiple wires to be predicted. The code has been applied, in particular, to allow optimization of the design of the suspension for the main mirrors in GEO 600, the German/United Kingdom gravitational wave detector. Results from one-, two- and four-wire suspensions are presented. For the GEO 600 detector it was concluded that a four-wire (two-loop) suspension was optimum.
