Abstract :
[en] This paper presents a new active isolation strategy and system which is dedicated to extended payloads, and compatible with particle accelerator environment. In comparison to the current isolation systems used in this environment, the system proposed does not contains any coil or elastomer and the supporting frame is dedicated to isolate long payloads from seismic motion. The concept proposed has been tested numerically on 3 and 6 degrees of freedom models, and validated experimentally on a one degree of freedom scaled test set-up. An attenuation of 40 dB at 1 Hz has been reached with the stage built. The complete description of performance and a noise budgeting are included in this paper.
