摘要

The EUV Imaging Spectrometer (EIS) on board the Hinode mission is capable of observing solar coronal plasma possibly in non-ionization-equilibrium. EUV emission lines from highly charged Fe ions observed in the solar corona are also produced in the Large Helical Device (LHD) and the compact electron beam ion trap (CoBIT). Time-dependent collisional-radiative model (CRM) for Fe ions is developed to diagnose those plasmas in the Sun and the laboratories by adopting the best available theoretical calculations of atomic parameters, as well as generating the experimental data.
