Title: Solar and LHD Plasma Diagnostics

Abstract

Japanese sun observing mission; Solar-B (Hinode) was launched on 23-Sep-06. The EUV Imaging Spectrometer (EIS) on board Solar-B will be able to observe, for the first time in Solar EUV observations, spectra and monochromatic images of non-ionization-equilibrium plasmas in the solar transition-region and corona at two-wavelength bands of 170 - 210Aa and 250 - 290Aa, with typical time-resolutions of 1 - 10 seconds. Time-dependent collisonal-radiative model has been developed to diagnose temperatures and densities of those plasmas in the outer atmospheres of the Sun. No systematic models yet exist for iron ions of L- and M-shells, which are very important for coronal plasma diagnostics. Atomic data of Fe X to Fe XV are surveyed and evaluated, and most recommended data are determined. Obtaining of the experimental data of iron ions are on-going. EUV spectra in the wavelengths of 170 - 190Aa were also taken by Large Helical Device (LHD) of NIFS, injecting iron TESPEL (tracer-encapsulated solid pellet)
