Preliminary results on two-dimensional diffusion in dusty plasma

POSTER

Abstract

We investigate self diffusion of particles in two dimensions (2D) using a dusty (complex) plasma. A 2D liquid containing $\sim 100$ particles is formed at the center of, and heated by, a toroidal gas of dust particles. The motions of individual dust particles are capturing using a video camera, allowing diffusion to be directly observed. This system will be characterized and the diffusion constant determined.
