An Eulerian, numerical simulation is used to model the launching of plasma waves in a non-neutral plasma that is confined in a Penning-Malmberg trap. The waves are launched by applying an oscillating potential to an electrically isolated sector at on

Selected experiments with nonneutral plasmas are discussed. These include the laser cooling of a pure ion plasma to a crystalline state, a measurement of the Salpeter enhancement factor for fusion in a strongly correlated plasma and the measurement o

Very weakly bound electron-ion pairs in a strong magnetic field are called guiding center drift atoms, since the electron dynamics can be treated by guiding center drift theory. Over a wide range of weak binding, the coupled electron-ion dynamics for

Recent experiments have characterized trapped-particle modes on a non-neutral plasma column [A. A. Kabantsev, C. F. Driscoll, T. J. Hilsabeck, T. M. O’Neil, and J. H. Yu, Phys. Rev. Lett. 87, 225002 (2001)], and in this paper we present a theoretic

In recent experiments ultracold plasmas were produced by photoionizing small clouds of laser cooled atoms. This paper presents the results of molecular dynamic simulations for the early time evolution of such plasmas. Contrary to earlier speculation,

Diocotron modes are discussed for a finite length nonneutral plasma column under the assumption of bounce averaged E×B drift dynamics and small Debye length. In this regime, which is common to experiments, Debye shielding forces the mode potential t

Radial transport produced by static nonaxisymmetric fields is thought to limit the confinement of non-neutral plasmas and experiments with applied asymmetries have verified that such fields do produce transport. A theoretical model of such transport

Despite their reputation, not all plasmas are difficult to confine. In fact, one kind of plasma can be kept for long times in a simple apparatus by means of static electric and magnetic fields. It is the kind of plasma that consists exclusively of pa

A normal mode analysis of perturbations on a stationary pattern formed by two-dimensional point vortices is carried out. The pattern is comprised of N equal vortices on a circle and one vortex of arbitrary strength in the center. The influence of an
