Ion-beam driven shock loading device is proposed to make efficient dynamic compaction of nanocrystal and non-equilibrium powders. Different form the conventional gas-guns and powder fire-guns, the repetitive application of shock pressure pulse to targeting materials and the fine control of pressure pulse are intrinsic features to the present approach. Since the generated plasmoid is electro-magnetically accelerated to launch the flyer, no limitation to flyer velocity is present. The laser doppler velocimetry is used to make real time measurement of copper flyer velocity. The efficiency is estimated to be about 6 % for conversion from the accumulated energy in the condenser bank to the kinetic energy of a flyer.
