Laboratory simulation of artificial plasma releases in space Original Research Article

The properties of laser-produced plasma are similar in many features to the properties of various space and astrophysical plasma releases of explosive nature. It allows to investigate the processes of an interaction of those natural plasmas with background media by the means of laboratory simulation. In the presented paper such simulative experiments with quasi-spherical plasma clouds (from small pellet target) and with plasma streams (from solid ones) are described. This experiments are related to the dynamics of collisionless expansion of exploding space plasmas into surrounding magnetized media at various Alfven-Mach numbers MA. A non-uniform media properties has been simulated also. Results are analysed in connection with dynamics of Supernova remnants in interstellar medium, Barium or others releases in geoplasma and possible disturbances of the latter caused by high-energy explosions.
