Analysis of EUV spectra from highly charged iron ions with a compact EBIT

For benchmark tests of the spectral analysis tool for solar plasma, applying the theoretical plasma radiation model to the laboratory plasma is important. In this paper, a compact-EBIT (Electron Beam Ion Trap) was adopted as the laboratory plasma, and extreme UV spectra of Fe ions were measured by the flat-field grazing-incidence spectrometer with no slit. In order to analyze the spectra from plasma generated by mono-energetic electron beam, our model was revised in term of an electron velocity distribution. Consequently, the measured spectra by the compact-EBIT were analyzed by our revised model.
