On the dynamics of the plasma entry and guiding in a straight magnetized filter of a pulsed vacuum arc
In this paper, a study of the plasma jet generated in a pulsed copper vacuum arc along a straight magnetized filter is presented. The ion saturation current and the plasma potential at different radial and axial positions and magnetic field intensities were measured using electrostatic probes. A the...
