Abstract

The process of plasma interaction with magnetic fields of an arch configuration plays a decisive role, for example, in coronal ejections in the sun or in the interaction of the solar wind with the Earth's magnetosphere. In this work, this process is simulated in laboratory conditions. The density of the plasma in the magnetic flow tube is determined by the vacuum arc discharge current, and the electrons are additionally heated under conditions of electron cyclotron resonance by the microwave radiation of the gyrotron. A technique for diagnostics and study of the characteristics of plasma flows is proposed. Test experiments were carried out, and a number of dependencies were obtained between the given parameters of the plasma flow density and electron cyclotron heating and the features of the plasma flow propagation.
