Abstract
The aim of this study is to reproduce a superalfvenic collisionless shock wave by using the Plasma Focus Facility as a plasma source. The experiments were performed on PF-3 Facility (Plasma Focus Filippov-type) at the level of energy supply up to 1 MJ. At compression of a current-plasma sheet to an axis in the stage of a plasma focus formation, the generation of cumulative plasma jets driven along the axis with a velocity ≈ 107 cm/s takes place. This directed driving is realized in the ambient plasma arisen as a result of the working gas ionization by the X-ray radiation of the plasma focus. The transversal magnetic field up to 2500 G was created by the magnetic system based on rare-earth magnets. The experimental conditions allowed us to perform experiments with Alfven Mach numberM A >-3.
