Small transverse magnetic quadrupole fields sharply degrade the confinement of non-neutral plasmas held in Malmberg-Penning traps. For example, a quadrupole magnetic field of only 0.02 G/cm doubles the diffusion rate in a trap with a 100 G axial magnetic field. Larger quadrupole fields noticeably change the shape of the plasma. The transport is greatest at an orbital resonance. These results cast doubt on plans to use magnetic quadrupole neutral atom traps to confine antihydrogen atoms created… 
The effects of neutral gas pressure and electron temperature on the dynamics of the electron diffusion gauge experiment electron plasma
The dynamics of pure, electron plasmas confined in cylindrically symmetric, Malmberg-Penning traps are strongly affected by imperfections in the trap fields and collisions with background gas
The Effect of Multipole-Enhanced Diffusion on the Joule Heating of a Cold Non-Neutral Plasma
Author(s): Chapman, Steven | Advisor(s): Fajans, Joel | Abstract: One proposed technique for trapping anti-atoms is to superimpose a Ioffe-Pritchard style magnetic-minimum neutral trap on a standard
Neoclassical transport processes in weakly collisional plasmas with fractured velocity distribution functions
Ripples in magnetic or electrostatic confinement fields give rise to trapping separatrices, and conventional neoclassical transport theory describes the collisional trapping/detrapping of particles
Particle-in-cell method for parallel dynamics in magnetized electron plasmas: Study of high-amplitude BGK modes
The numerical technique developed has been employed to simulate the formation and long-term evolution of large-amplitude electrostatic waves experimentally observed in electron plasmas confined in a Penning trap and furnish clear evidences of the close relationship between the observed nonlinear structures and the Bernstein-Greene-Kruskal modes.
Malmberg¿Penning and Minimum-B trap compatibility: the advantages of higher-order multipole traps
Abstract The ATHENA and ATRAP collaborations have recently created large numbers of untrapped anti-hydrogen atoms. The most commonly suggested scheme for trapping the anti-hydrogen is to use a

This paper will motivate the current effort to make cold antiHydrogen, explain how antihydrogen is currently made, and how and why it is attempting to trap it, and discuss what kind of measurements are planned to gain new insights into the unexplained asymmetry between matter and antimatter in the universe.


Two regimes of asymmetry-induced transport in non-neutral plasmas
New measurements in pure-electron plasmas demonstrate two separate transport regimes depending on the particle bounce-to-rotation ratio, or rigidity, which scales as V(2)(a)R-2 and does not depend directly on the rigidity.
Theory of asymmetry-induced transport in a non-neutral plasma
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
Equilibrium of highly asymmetric non-neutral plasmas
Pure electron plasmas are usually confined within cylindrically symmetric Penning–Malmberg traps. When azimuthally asymmetric potentials are imposed on the trap walls, the plasmas deform into
Pure electron plasmas in asymmetric traps
Pure electron plasmas are routinely confined within cylindrically symmetric Penning traps. In this paper the static and dynamic properties of plasmas confined in traps with applied electric field
Electron Cooling of Protons in a Nested Penning Trap.
The demonstrated interaction of electrons and protons at very low relative velocities, where recombination is predicted to be most rapid, indicates that this may be a route towards the study of low temperature recombination.
Length-Dependent Containment of a Pure Electron-Plasma Column
The long-time containment of pure electron-plasma columns has been found to depend strongly on the plasma length $L$, as well as on the axial magnetic field $B$. Plasma evolution times are observed
Heating of an Electron Plasma by Oscillating Sheaths.
The first unambiguous measurements of a bounce-resonance effect in a non-neutral plasma are presented. Two striking signatures are observed when a magnetized electron column is heated by oscillating

A technique is presented for measuring the parallel energy distribution of magnetically confined electrons in a cylindrically symmetric pure electron plasma. In essence, the technique measures how

A simple model is presented of a finite length electron plasma column supporting a small amplitude diocotron wave with mode number m=1. The electrons are contained inside conducting cylinders in an
Long-Time Containment of a Pure Electron Plasma
A pure electron plasma has been confined in cylindrical geometry for many minutes. Confinement scalings with background pressure and magnetic field show that the maximum confinement times, while
