Note (General): To make use of an ion engine as a propulsion device for a spacecraft, it is important to know if the charged particles exhausted from the engine might make such influences on the mission of the spacecraft as radio wave interference in communication or experiments, contamination for sensors, spacecraft electric potential raising etc. In this point of view, the nature of the exhausted beam is required to be studied in details. This paper presents the relations between engine operation parameters and the properties of the beams exhausted from a 5cm electronbombardment mercury ion engine. The process of the neutralization of the beam is considered. Space distributions of ion and electron current density of the beams were experimentally obtained using a Faraday cup and a flat plate probe. It is assured that the shapes of the ion current density distributions are intimately related to the perveance of the ion flow. This is deduced from the dimensional analysis of basic equations for ion flow. The space and floating potentials of the beam were measured using an emission probe and a flat plate. The space potential is determined mainly by the space charge limited condition of electron current between a neutralizer and the beam edge.
