Abstract

This paper describes three-dimensional numerical simulations and Radio Frequency (RF) measurements of wave propagation in the microwave-heated magnetized plasmas of ion sources. Our 3D Full-wave numerical model considers the inhomogeneous and anisotropic magnetized plasma medium in the 'cold' plasma approximation. Maxwell's equations have been solved through the Finite Element Method (FEM). For the first time, by means of a two-pin RF probe, it has been possible to measure the electromagnetic field in a compact plasma trap where the experiment conditions resemble very closely the features of a common ion source for a direct comparison with the simulations. The numerical model has been supported by direct measurements of the plasma density profiles performed for different magnetic field configurations.
