The design and operational characteristics of an in-house-built 5-cm- diam Kaufman-type ion engine that was used to evaluate diagnostic methods is presented. The discharge of the ion engine was investigated and analyzed by employing various types of material probes. The emissive probe was used to determine the beam potential, the electron temperature, and the ion impingement current density. The double Langmuir probe was used to determine electron temperature and ion impingement current density for cross correlation between probes. The analytical and experimental results are compared and discussed.
