Variations in magnetic or electrostatic confinement fields give rise to trapping separatrices, and neoclassical transport theory analyzes effects from collision-induced separatrix crossings. Experiments on pure electron plasmas now quantitatively characterize a broad range of transport and wave damping effects due to "chaotic" separatrix crossings, which occur due to equilibrium plasma rotation across θ-ruffled separatrices, and due to wave-induced separatrix fluctuations.

Neoclassical transport and plasma mode damping caused by collisionless scattering across an asymmetric separatrix
Plasma loss due to apparatus asymmetries is a ubiquitous phenomenon in magnetic plasma confinement. When the plasma equilibrium has locally-trapped particle populations partitioned by a separatrix
Plasma Heating due to Cyclic Diffusion across a Separatrix.
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 across a partial trapping
Enhanced superbanana transport caused by chaotic scattering across an asymmetric separatrix
This paper discusses a novel “chaotic” form of superbanana transport and compares the theory to experiments on non-neutral plasmas. Superbanana transport is caused by particles that cross local
Superbanana transport in the collisional heating of a plasma column forced across a squeeze potential
When weakly collisional plasmas have locally trapped particle populations, perturbations to the plasma equilibrium (such as waves or static field-errors) can induce phase-space discontinuities in the
Particle fluxes through the separatrix in the trapped particle diocotron mode
In the trapped particle diocotron mode, the trapped particles undergo E × B drift motion in a uniform B field. Since such a flow is incompressible one is tempted to assume that the trapped particle
Application of chaos theory to the particle dynamics of asymmetry-induced transport
The techniques of chaos theory are employed in an effort to better understand the complex single-particle dynamics of asymmetry-induced transport in non-neutral plasmas. The dynamical equations are
Stabilizing effect of a nonresonant radio frequency drive on the m=1 diocotron instability
It has been experimentally shown that the rotation radius of a non-neutral plasma column around the longitudinal axis of a Malmberg–Penning trap experiences a growth in amplitude (m=1 diocotron
Dependence of enhanced asymmetry-induced transport on collision frequency
A single-particle code with collisional effects is used to study how asymmetry-induced radial transport in a non-neutral plasma depends on collision frequency. For asymmetries of the form ϕ1(r)
First experiments with e - /H - plasmas: Enhanced centrifugal separation from diocotron mode damping
Negative hydrogen ions are produced and contained within a room-temperature electron plasma, by dissociative electron attachment onto exited neutrals. We observe a strongly enhanced centrifugal
Diocotron modulation in an electron plasma through continuous radio-frequency excitation
The application of a radio-frequency (RF) excitation to any electrode of a Penning-Malmberg trap may result in significant electron heating and ionization of the residual gas with the formation of a
