Abstract
Ultimate seismic isolation at low frequencies is necessary for the 3rd generation gravitational wave detectors. To isolate low-frequency seismic motion, we suggest the hybrid two-stage system with an inverted pendulum and a Roberts linkage. It is possible to tune each resonant frequency independently due to the different main parameters; load and center of gravity.
