AB - Electron Cyclotron Resonance (ECR) plasmas with high density and high temperature are required by the injectors for the Accelerators and by interdisciplinary studies in Astrophysics and Nuclear Astrophysics. The magnetic traps need a very fine analysis of plasma conditions in terms of density, temperature and ionisation state, not allowed by the present diagnostic methods (imaging, low resolution spectroscopy not spatially resolved). We here describe the results routinely obtained in Astrophysics with high resolution spectroscopy, largely used to analyse astrophysical plasmas in the visible range, which allows to determine physical parameters of stars as surface gravity, effective temperature, chemical abundances. In addition we show that polarimetry is the only technique to derive the morphology of stellar magnetic fields, whose knowledge is necessary for a correct interpretation of spectra from magnetised plasmas. An application of these non-invasive methods to minimum-B ECR plasma concerning optical emission is discussed in view of a better comprehension of the plasma structure, magnetic confinement properties and heating processes.
