Small Particle Acceleration by Mini-Railgun

Mini-Railgun with about 800J power supply was made to launch a small particle at about 100m/s for the purpose of machining. Although the structure of the Mini-Railgun is the same as a conventional railgun, the acceleration mechanism was found to be different from that of the conventional one. The experimental data of the velocity and the pressure agreed well with those estimated from the gasgun model.
