A Simple Design Erosional Plasma Gun Made of a Coaxial Cable with Polyethylene Insulation

Abstract

A compact pulsed plasma generator of simple design made of a coaxial cable with polyethylene insulation has been described. A plasma gun generates a cloud of carbon-hydrogen plasma with an electron density of more than 10¹³ cm^–3, including in a magnetic field produced of up to 500 G and also in the presence of the background plasma with a density of about 10¹² cm^–3, which is produced by an independent source. The high resource of the gun and stability of plasma parameters from one pulse to another allows using such a gun in laboratory experiments simulating dynamic processes in space.
