TL;DR: In this article, the authors present plans for the creation and diagnosis of pair plasmas in a stellarator, based on extrapolation of the results from the Columbia Non-neutral Torus stellarator.
Journal ArticleDOI
Measurement of Landau damping and the evolution to a BGK equilibrium.
TL;DR: Linear Landau damping and nonlinear wave-particle trapping oscillations are observed with standing plasma waves in a trapped pure electron plasma, approaching a steady state, as predicted by O'Neil in 1965.
Journal ArticleDOI
Dipole Enhancement of Positron Binding to Molecules
TL;DR: Measurements of positron-molecule binding energies are made for molecules with large permanent dipole moments, by studying vibrational-Feshbach-mediated annihilation resonances as a function of incident positron energy.
