Description

In this article, we present the design of four-channel Ultra-Fast Charge eXchange Recombination Spectroscopy (UF-CXRS) diagnostic on EAST (Experimental Advanced Superconducting Tokamak) device. This diagnostic is based on the active charge exchange to diagnose ion temperature with a time resolution at the order to 10 us and a spatial resolution of 1 cm. It has a view range from core to edge plasma with a minimum ion temperature of 0.38 kev. The design of the main components are carefully discussed, including the dichroic mirror light path, the fiber, the spectrometer, and the customered lens. All of this parameter will make it be a keen tool for ion temperature diagnosing. (author)
