This article presents experimental data on measuring the electron temperature and plasma concentration in the radial direction on a plasma-beam setup. The plasma parameters were determined using an automated diagnostic system based on an electric probe for two working gases, hydrogen and helium. The dependences of the electron temperature and plasma density on the change in the electron beam power and working gas pressure are determined. It is shown that with an increase in the power of the electron beam, the electron temperature in the radial direction does not change for both working media, and the maximum plasma concentration in the facility was recorded at the highest gas pressure closer to the center of the beam and amounted to 5·1016 m−3 for hydrogen and 5·1017 m−3 for helium.
