Influence of magnetic field and density of environment on collimation of laboratory jet

Abstract

Abstract In this work a numerical simulation of the propagation of a plasma bunch in the experimental plasma focus facility was carried out to determine the parameters influencing on the value of an opening angle. Both the experiment and the numerical simulations are supposed to have the same dimensionless parameters as astrophysical jets. The dependence of the jet opening angle on the magnitude of the magnetic field and the ratio of the densities of the jet itself and the surrounding plasma was investigated. Due to the obtained results, it became possible to determine the dominant factor responsible for jet collimation.
