Vibration Isolation of a Gravitational wave detector
According to Einstein’s general theory of relativity, astronomical events like coalescence of black holes and supernovas generate gravitational waves which distort space. Several instruments have been constructed to detect these waves on Earth. The basic principle of these detectors is to measure extremely precisely the distance between far away mirrors, which must be extremely well isolated from environmental disturbances. This stability is achieved by combining several isolation stages. The objective of the thesis is to identify possible margins of improvement of the current design. The work will include the development of simplified mathematical model of the suspension chain, and possibly a scaled demonstrator.
