Electron cyclotron resonance discharges can be applied successfully for wall conditioning in controlled nuclear fusion orientated devices and in the production of high temperature superconducting materials. Moreover, they have been used very successfully to generate plasmas in ion sources, especially for ion beams with high charge numbers. A detailed knowledge of the plasma parameters is fundamental for optimal wall processing and for the generation of optimum ion beams. Details are given of an experimental study on a discharge, applying mainly the rotatable electrical double probe to determine ion temperatures in magnetised plasmas, as well as the electron temperature and the ion density. The method allows the determination of the ion temperature component in the plane perpendicular to the magnetic field direction. The value of this ion temperature in the plasma is crucial to the quality of an ion beam.
