| Abstract: | The divertor plasma characteristics are studied by means of electro-motion scanning 4-probes in the outer divertor chamber and the fixed flush probe arrays on the 4 divertor neutralization plates at the same toroidal cross-section in the HL-2A tokamak.They provide important parameters for investigation of distribution and asymmetric of plasma parameter in the divertor.The profiles of energy or particle flow and their decay lengths can be estimated by the target temperature and density.They are very useful to investigate plasma behavior and physical characteristic in the divertor mode.These results identify that divertor can improve the particle confinement. |
