使用高分辨率光谱仪结合图像扩展器光学系统测量了MAP-II偏滤器模拟器等离子体中的离子温度和流速，该系统还可以校正球面镜中的像散。在拟合过程中考虑了类氢氦线的精细结构。这使得光谱学和马赫探针之间的绝对流速测量值的比较成为可能。
Ion temperature and flow velocity in the MAP-II divertor simulator plasmas were measured using a high-resolution spectrometer combined with image expander optics which can also correct the astigmatism in spherical mirrors. The fine structure of the hydrogenic helium line was taken into consideration in the fitting procedures. This enables the comparison of the absolute flow velocity measurements between spectroscopy and the Mach probe.
