In order to allow the advanced interpretation of the X-ray spectra registered by the high-resolution crystal KX1 spectrometer on the JET with an ITER-like wall, especially to determine how the relative emission contributions of tungsten and molybdenum ions change during a JET discharge, the X-ray spectra have been carefully modeled over a narrow wavelength range. The simulations have been done in the framework of Collisional–Radiative model implemented in Flexible Atomic Code for an electron density (n e = 2.5 × 10 19 m −3 ), and electron temperatures between T e = 3.0 keV and T e = 4.5 keV, typical for JET. Moreover, performed detailed analysis in the framework of the proposed procedure can be useful in determining temperature of a high temperature plasma generated in tokamaks.

托卡马克等离子体中钨和钼离子发射的高分辨率 X 射线光谱的理论建模

为了对具有类似 ITER 壁的 JET 上的高分辨率晶体 KX1 光谱仪记录的 X 射线光谱进行高级解释，特别是确定钨和钼离子的相对发射贡献在 JET 放电过程中如何变化，X 射线光谱已在窄波长范围内仔细建模。对于电子密度 (ne = 2.5 × 10 19 m -3 ) 和电子温度在 Te = 3.0 keV 和 T e = 4.5 keV 之间，在灵活原子代码中实现的碰撞-辐射模型框架中进行了模拟，典型的 JET。此外，在所提出程序的框架内进行的详细分析可用于确定托卡马克中产生的高温等离子体的温度。
