To ensure the efficient use of such engines, tasks related to the diagnostics of the engine plasma jet are of particular importance. Measuring the parameters of the jet plasma allows us to diagnose the operation of the engine itself, determine its efficiency, and calculate the impact of the engine plasma jet on the onboard devices of spacecraft. One of the most important tasks is to study the charge composition of ions in the plasma of the electric propulsion jet. This paper presents a study of the method for measuring the charge composition of the plasma of a Hall-type electric rocket engine jet.
