A four-testing-channel Ultra-Fast Charge eXchange Recombination Spectroscopy
(UF-CXRS) diagnostic is under developing on the EAST tokamak and a 128-channel
upgraded one will be combined with the existing 128-channel Beam Emission
Spectroscopy to diagnose plasma pressure. This diagnostic is based on the active charge
exchange to measure ion temperature with a time resolution at the order of 1 μs and a
spatial resolution of 1 cm. The main component design and selection together with
simulations and test results are presented in this report. The theoretical estimation of the
emission photon flux which can reach the detector of UF-CXRS system has been carried
out, proving the feasibility of the whole design.
