Preliminary Investigations of the Rotational Mode of a Plasma Dust Ring

POSTER

Abstract

The rotational mode of a strongly-coupled dusty plasma ring was studied. The particles rotated within the ring shaped potential well that was formed using a variable aperture with a center post. Various aperture sizes were applied. Particle position data from the rotating dust ring was analyzed and results were compared with predictions of normal mode calculations.
