INVESTIGATION OF FREE DECAYING TURBULENCE IN A TRAPPED PURE ELECTRON PLASMA
An electron plasma confined in a Malmberg-Penning trap can be a good experimental setup for the study of the two-dimensional fluid dynamics, since a magnetized plasma in this geometry behaves like an eulerian fluid in a wide range of experimental conditions. Plasma turbulence is triggered by the diocotron instability. Here, the results of a Fourier spectral analysis of the energy and enstrophy distributions are reported and interpreted using theoretical models of two dimensional turbulence.
