在本文中，我们设计了一种四通道超快速电荷交换复合光谱（UF-CXRS）在EAST托卡马克上的诊断。这种诊断是基于主动电荷交换来测量离子温度，时间分辨率为1 μ s，空间分辨率为1 cm。对主要部件的设计进行了详细的讨论，包括二向镜光路、光纤、光谱仪和定制透镜。对发射光子通量进行了理论估计，证明了整个设计的可行性。
In this article, we present the design of a four-channel Ultra-Fast Charge eXchange Recombination Spectroscopy (UF-CXRS) diagnostic on the EAST tokamak. This diagnostic is based on the active charge exchange to measure ion temperature with a time resolution at the order of 1 μ s and a spatial resolution of 1 cm. The design of the main components is carefully discussed, including the dichroic mirror light path, the fiber, the spectrometer and the customized lens. The theoretical estimation of the emission photon flux has been carried out, proving the feasibility of the whole design.
