The  first self developed plasma dynamic micro particle accelerator was  checked and accepted in Center for Space Science and Applied Research,  CAS, recently. It’s  the forth facility besides those in Technical University of Munich,  Institute of Technology of Tokyo, Auburn University and America, and add  a new member to our domestic family of debris launchers.

The  major parts of the accelerator are coaxial electrodes and compressing  coils. The electrodes, powered by high voltage capacitor banks can  discharge and generate hyper velocity plasma, which is then compressed  into high density by the compressing coils and drag the particles in the  nozzle up to 1 to 15 km/s. Compared with other debris launchers like  light gas gun, laser driven accelerator and electrostatic dust  accelerator, the plasma dynamic accelerator is more outstanding for its  larger range of particle sizes and velocities, applicability to both  metal and nonmetal particles, and convenience for micro debris  simulation.
