An argon laser interferometer for the detection of gravitational radiation
Abstract
A gravitational radiation antenna, consisting of a Michelson interferometer illuminated with an argon laser, is being developed. A first stage has been reached with the construction of a small prototype of 3 m arm length. This prototype was used to locate and study various noise sources and other disturbances, which would restrict signal perceptibility. From an analysis of these disturbances, the demands on apparatus components have been estimated. Some constructional details are given, as well as suggestions for improvement aimed at a future interferometer of increased base length, with the prospect of successful operation.
