This paper describes design and installation of a charge-exchange recombination spectroscopy (CXRS) system in Heliotron J. In this system, two tangential-heating neutral beams are used for plasma heating as well as the diagnostic beams. The sightlines are set to be parallel to the magnetic axis to achieve high spatial resolution. The spatial resolution is Δ‹r/a› ∼ 0.05 for a measurement area of 0.37< ‹r/a› < 0.79. We adopted a Czerny-Turner monochromator, whose dispersion is 0.74 nm/mm. We applied this system is applied to an NBI plasma and the time evolution of the ion temperature and the toroidal rotation velocity profile are successfully obtained.
