In recent years, there has been a wealth of new science involving low-energy antimatter (ie,
positrons and antiprotons) at energies ranging from 10 2 to less than 10-3 eV. Much of this …

Progress in the ability to accumulate and cool positrons and antiprotons is enabling new
scientific and technological opportunities. The driver for this work is plasma physics research …

Over the last quarter of this century, revolutionary advances have been made both in kind
and in precision in the application of particle traps to the study of thephysics of charged …

Linear Landau damping and nonlinear wave-particle trapping oscillations are observed with
standing plasma waves in a trapped pure electron plasma. For low wave amplitudes, the …

Magnetic fields influence ion transport in plasmas. Straightforward comparisons of
experimental measurements with plasma theories are complicated when the plasma is …

Cold-fluid and warm-fluid electrostatic plasma modes of magnetized nonuniform plasmas
are determined as eigenfunctions of an integral equation describing the perturbed fluid …

Thermally excited charge fluctuations in pure electron plasma columns provide a diagnostic
for the plasma temperature over a range of 0.05< k BT< 10 eV⁠. Three different …

Significant variations in the density and potential along the axis of a pure electron plasma in
the Columbia Non-neutral Torus (CNT) stellarator have now been measured. Large …

Abstract The ALPHA (Antihydrogen Laser Physics Apparatus) collaboration creates and
performs precise measurements on antihydrogen to test Charge-Parity-Time (CPT) …

Methods are described to create, store, manipulate and characterize positron plasmas.
Emphasis is placed on the so-called buffer-gas positron trapping scheme for positron …
