The Versatile Ion Source (VIS) is a permanent magnet version of the TRIPS source with a simplified and robust extraction system. It operates up to 80 kV without a bulky high voltage platform, producing multi-mA beams of protons and H2+. The description of the source design and the preliminary performance will be presented. An outline of the forthcoming developments is given, with particular care to the use of a low loss dc break and to the use of a travelling wave tube amplifier to get an optimum matching between the microwave generator and the plasma.

Experimental measurements of the scattering parameters carried out in microwave discharge and ECR ion sources will be hereinafter described. The details of different tests performed on a 14.5 GHz operating ECR ion source and on a plasma reactor operating at 2.45 GHz for enviromental purposes are reported. In particular this last device, equipped with a Langmuir probe, has been very useful to verify the presence of stationary waves and to study the electromagnetic wave propagation in plasmas. The evaluation of the Q factor with and without plasma and the determination of its variation with plasma density and temperature will be also presented.
