THE INTERFEROMETER NETWORK LIGO – Hanford, WA A network of 4 (5) GW detectors GEO600, Hannover, Germany LIGO – Livingston, LA VIRGO, Cascina (PI), Italy BUILDING UP A “SINGLE MACHINE” Virgo and LSC (LIGO ScienEfic CollaboraEon)* have signed an MoU for full data sharing and common authorship of science papers. *GEO600 part of the LSC
GW hunters are heirsto several great traditions:- high precision mechanical experiments (Cavendish, Eotvos, Dicke..)detection of weak forces applied on mechanical test bodies- precision optical measurements (Michelson, laser developers…)- operation of ultraprecise measurement systems (microwavepioneers of World War II, Weber)- very low temperature physics (Onnes, BCS, Josephson)superfluids and superconductors technology
