 note = {A new charge exchange spectroscopic technique using a Fabry-Perot spectrometer has been developed to increase the photon flux at the detector and improve the time resolution of ion temperature and plasma rotation velocity measurements. The spectral resolution is obtained by arranging two dimensional fiber optics and a two dimensional detector at the focal plane of a coupled lens located on both sides of a Fabry-Perot spectrometer. The effective finesse of the Fabry-Perot interferometer in this system is 14. The time evolution of the ion temperature is obtained with a time resolution of 125 mu s and with the spatial resolution of 3 cm (8channels).},
