Abstract

A plasma jet based on a high-current pseudo-spark discharge has been developed. A pseudo-spark discharge (PSD) is a high-current glow-like discharge, which is formed on the left side of the minimum of the Paschen curve. Although the discharge current exceeds several tens of kiloamperes, the discharge retains the glow mode because of the hollow cathode effect. The PSD is formed with a large number of arc channels, which are usually narrow. Consequently, the PSD has a large cross section. In this study, the PSD anode has a hole with a larger diameter than that of the cathode in order to generate a plasma jet. The plasma is effectively accelerated by the electromagnetic force due to the modified shape of electrodes. The electron temperature and density of the plasma jet were measured by a double probe technique. At the discharge current of 10 kA, the temperature of the plasma jet reached approximately 1.9 eV and the density was of the order of 1014 cm-3 at the distance of 72 mm from the anode.
