| Abstract: | In order to obtain the important plasma parameters such as ion temperatures,rotate velocity and their profiles,a CXRS(charge exchange recombination spectroscopy) diagnosis was developed in HL-2A tokamak.In order to get the diagnostics signals with enough signal-to-noise ratio,the EMCCD detector suitable for the weak signal and the dedicated optical collection system converging light flux effectively were utilized.The experiment result proved that the design was feasible. |
