Abstract :
The motion of particles in a complex (dusty) plasma agitated by a shock wave was resolved with a high-speed video camera. The shock melted the initially crystalline monolayer. Macroscopic parameters such as number density, kinetic temperature, and flow velocity were determined. The shock caused a 30-fold jump in kinetic temperature. The width of the shock front was found to be on the order of the interparticle distance.
