Abstract :
A realistic, pulse-to-pulse, simulation is done to evaluate performance of an orbit feedback system in final focus system for future linear colliders. Accumulation of errors and long time stability of the system including time evolution of ground movement are estimated by this simulation. The result of simulation confirms that the orbit feedback system can maintain nanometer beam size at a colliding point and can keep beams in head-on collision
