One of the accelerator projects currently being studied is the construction of a linear collider composed of two 16 km arms face to face. Nominal luminosity is of the order of 1034cm-2s-1. For such a performance, one must take into account the ground nanodisplacements induced by cultural noise. The machine optical elements must be stable and in particular the movements of the two final focus magnets must be smaller than a third of the beam size. This can only be achieved through active stabilization. The current mechatronics study focuses on three subjects. First, one needs adapted sensors and actuators to measure nanodisplacements and achieve the required stabilization. Secondly, mechanical models are being tested to help optimize the final design. In a third part, a feedback loop is being developed to obtain the vibration stabilization of the whole system.
