Abstract
A diagnostic method and system for measuring potential and electric field of plasma are provided. According to operation parameters of a magnetic confinement fusion device and relevant parameter data of a plurality of candidate particle elements, signal-noise ratios are calculated. to select a neutral beam particle element. Beam trajectories varying in incident velocity, incident angle and sampling area are obtained by iterative calculation, and a preset parameter which enables the beam trajectories to pass through an entrance slit of an analyzer is obtained. A neutral beam that meets the preset parameter is injected into the plasma. An energy of the primary beam generated by collision ionization in a sampling area is measured, and potential of the sampling area is obtained according to law of conservation of energy. Sampling areas are detected to obtain potential spatial distribution of the plasma and a radial electric field, and the diagnostic is finished.
