This article describes an erosion test facility which is based on exploding-foil and exploding-wire technology. The large controllable energy released by exploding foils and exploding wires is utilized to launch 100–8000 μ particles to velocities ranging from 250 to 7000 m/sec. Specific features which are unique to the facility are the high degree of aiming accuracy, high-speed framing photography of the particle in flight, and the use of simple, expendable launch assemblies to provide a low cost, flexible, and reliable method for obtaining small-particle impact data.
