A STUDY OF THE COLLISIONLESS INTERACTION OF INTERPENETRATING SUPER-ALFVEN PLASMA FLOWS

The authors attempt to obtain plasma parameters as required for effective magnetic laminar mechanism (MLM) interaction, while examining the collisionless interaction of an expanding laser-plasma cloud with a magnetized background for high mach numbers (M /sub A/ greater than or equal to 5) and the interaction parameter greater than 1. The experiments were preformed with the KI-1 apparatus for simulating astrophysical plasma processes. The main components were the 1-kJ CO/sub 2/ laser and a high vacuum chamber of diameter 1.2 m and length 5 m fitted with a pulsed background plasma source. Particular attention was given to eliminating the effects from ordinary Coulomb collisions, and various forms of collisional interaction were examined including Coulomb, screened nuclear repulsion, polarization-type attraction, and charge transfer.

Laboratory simulation of plasma jet propagation across geomagnetic field at presence of plasma background

Abstract In the experiments with laser-produced plasma jets the main processes of their interaction with transverse magnetic field were studied to simulate various plasma injections in space and the effect of influence of dilute background plasma onto electric drift motion of jet was reproduced and investigated experimentally for the first time
