碰撞辐射模型在光谱模拟中的应用
Application of collisional-radiative model in spectral simulation
摘要
Abstract
The extremely high temperature of controlled fusion plasmas makes direct temperature measurements impractical.However,their emission spectra contain abundant diagnostic information,such as plasma density and temperature.Tungsten has been selected as a divertor and first wall material in fusion devices due to its excellent physical and chemical properties.Interactions between tungsten and the plasma result in the generation of tungsten ions,whose radiation spectra can be utilized to diagnose various plasma parameters.From a theoretical standpoint,tungsten is a heavy element where relativistic effects,electron correlation,and quantum electrodynamic(QED)effects are significant.Therefore,it is essential to investigate the fine structure energy levels and radiative transition properties of tungsten ions.This paper provides a review of our research group's work on the calculation of fine structure energy levels,radiative transition characteristics,and spectral simulation of tungsten ions based on the collisional-radiative model.关键词
