Abstract
We have produced a strongly coupled non-neutral 9Be+ ion plasma with a coupling parameter of approximately 100 or greater..The ions were spatially confined by a Penning trap [Penning 1936, Dehmelt 1967, 1969, Wineland et al. 1983] and cooled and compressed using laser cooling [Itano and Wineland 1982]. Measurements were made of the plasma shape, rotation frequency, density and temperature. In this paper we describe the experimental confinement geometry, the laser cooling of ions and the experimental data which are compared with theoretical predictions. Future experiments to measure the plasma static structure function, measure ion diffusion, and improve the temperature measurement are discussed.
