Abstract

The paper presents the results of one of the first experimental campaigns on the experimental stand HPS-2 (helicon plasma source, 2 kW) for studying the plasma-material interactions, designed and manufactured at the NRC “Kurchatov Institute”. The discharge parameters were measured using a set of probe diagnostics. Based on the obtained experimental data, the optimal values of the magnetic field and the flow rate of the working gas for this configuration of the device were selected, the possibility of obtaining plasma with a density of about 1011 cm-3 was demonstrated. The influence of the position of the RF antenna in a decreasing magnetic field relative to its maximum was studied.
