Description
There are no other large instruments that are limited so much by availability of materials like the Earth based GW detectors. Thermal noise and optical absorption in mirrors and their suspensions are a strong limiting factor for future upgrades of existig detectors and also in new projects like Einstein Telescope. A new group at the Insitut Lumière Matière, Lyon, has been formed with the aim to study the origin of thermal noise in amorphous materials and to develop the technology of sapphire for large missor substrates and monolithic suspensions.
