Nanometer scale active ground motion isolator

Abstract : Vibration isolation is a critical issue in various precision engineering fields. A new design of an activeisolation system operating heavy loads (up to 50 kg) is presented in this work. This system provides stateof the art vibration isolation at the nanometer scale for magnets of a future particle accelerator and is more compact than other studies in this field. The choice of sensors and actuators, the mechanical designand the acquisition electronics are investigated in order to reject ground motion efficiently. A dynamic experimental characterization is performed. Based on the identified model, a specific controller, givingan attenuation between 10 Hz and 100 Hz was designed and experimentally qualified.
