| Outline of Final Research Achievements |
The major results of this study are as follows; (1) Development of procedures to calculate emission line intensities under arbitrary electron energy distributions by using atomic data. (2) Derivation of fractions of high energy electrons from soft x-ray spectra observed in the large helical device, and confirmation that the developed model is valid with these emissions. (3) Identification of suitable lines for thermal non-equilibrium plasma diagnostics by measurements of the next solar space-borne telescope “Solar-C_EUVST”.

| Academic Significance and Societal Importance of the Research Achievements |
本研究により、太陽フレアのみならず衝突プラズマ一般において、過去および将来の紫外線・X線分光観測から高エネルギー電子の定量評価が可能な環境が整ったことが大きな意義となる。ただし、適切な輝線の組み合わせが限られること、またインプットとなる原子データの不定性により高エネルギー電子の誤差推定が難しくなることがあげられる。したがって、さらなる原子過程の理解と理論的・実験的な原子モデルの精度向上が今後の課題として挙げられる。
