Abstract
The experiment use Doppler shift spectroscopy method to measure neutral beam energy component H(E) ,H(E/2) ,H(E/3) on HL-2A Tokamak. With the aid of CXRS system,we obtain Ha spectrum which are emitted by neutral beam. Because of the Doppler effect,the different energy hydrogen atom emit Ha spectrum,which have different frequency shift. Then the multi-peak Ha spectrum is obtained. A method based on Matlab has been proposed to fit raw data and calculate three beam energy components.关键词
