During the last fifty years, nonneutral plasma physics has developed into a definite subfield
of basic research, whose main focus has been on the collective properties of systems …

Inviscid spatial Landau damping is studied experimentally for the case of oscillatory motion
of a two-dimensional vortex about its elliptical equilibrium in the presence of an applied …

This paper presents the first experimental confirmation of a new theory predicting enhanced
drag due to long-range collisions in a magnetized plasma. The experiments measure …

We present damping measurements of axial plasma waves in magnetized, multispecies ion
plasmas. At high temperatures T≳ 10− 2 eV, collisionless Landau damping dominates …

One-dimensional particle simulations have been conducted to study the interaction between
a radio-frequency electrostatic wave and electrons with bouncing motion. It is shown that …

We observe plasma heating due to collisional diffusion across a separatrix when a
magnesium ion column in a Penning-Malmberg trap is cyclically pushed back and forth …

Cyclotron modes are studied on rigid rotor, multi-species ion plasmas confined in a Penning-
Malmberg trap. Collective effects and radial electric fields shift the cyclotron mode …
