Description
Ultimate seismic isolation at low frequencies is necessary for 3rd-generation gravitational-wave detectors. To isolate low-frequency seismic motions, we suggest a hybrid two-stage system with an inverted pendulum and a Roberts linkage. It is possible to tune each resonant frequency independently. We plan to make a prototype hybrid suspension in the TAMA facility.
