Active vibration suppression R+D for the next linear collider

The nanometer scale beam sizes at the interaction point in linear colliders limit the allowable motion of the final focus magnets.

Description
Summary:The nanometer scale beam sizes at the interaction point in linear colliders limit the allowable motion of the final focus magnets. We have constructed a prototype system to investigate the use of active vibration damping to control magnet motion. Inertial sensors are used to measure the position of a test mass, and a DSP based system provides feedback using electrostatic pushers. Simulation and experimental results for the control of a mechanically simple system are presented.
