Longitudinal Waves in Strongly Coupled Two-ring Dust Chains

POSTER

Abstract

A strongly coupled two-ring dust chain of micron sized particles is created experimentally in an R-F generated plasma. The two rings with different radii are confined in a circular potential well and longitudinal dust lattice waves are transmitted along the chain. The dispersion relation is measured and compared to theory.
