Fe XVII and the ?-Distributions: Diagnostics with Hinode EIS
Original language description
The intensities of the spectral lines in the solar corona can be affected by the presence of electron non-thermal distributions. We have looked for the EUV lines of Fe ions in the spectral range corresponding to the EIS detectors which allow us to diagnose the kappa-distributions. We have found that the ratios of Fe XVII lines in the EIS spectral ranges have no sensitivity to electron density which gives the best opportunity for diagnostics. A set of synthetic spectra for different values of the parameter kappa of non-thermal ?-distribution, electron density and the mean energy of distribution have been computed. The line ratios with the best sensitivity to the shape of the distribution function have been selected and diagnostics of the parameter kappahave been proposed. The possibilities to diagnose the kappa distributions from EIS observations are discussed.
