Estudio de una onda lenta de gran amplitud en el sistema chorro - plasma por ondas de prueba

J. Ruiz-Camacho

Abstract


A theoretical and experimental study of the potential well that takes place behind the shock wave excited in an ion-beam plasma system was performed. The space distribution of the potential well was calculated with the fluid theory where, in addition to the two ionic species, two electronic species with different temperatures and densities were included. The width and depth of the well, which were measured experimentally, were compared with the theoretical results. Amplification of locally excited test waves within the plasma was measured, allowing us to calculate the ion beam acceleration in the potential well. From these measurements we calculated the space variation of ion beam velocity within the well.
