The influence of plume angle and energy on the mass separation of plasma beam

Plasma optical mass separation is an important innovation in the field of isotopes separation. The magnetic field in the separation region only plays the role of magnetizing plasma and guiding the beam flow direction. The ion trajectory in the separation region containing only radial electric field is the focus of the current research. The plume angle and energy of the plasma beam also determine the effect of beam mass separation. Based on the equation of motion of the ion in the electric field and the mechanism of obtaining the circumferential velocity in the azimuthator, the trajectories of the lithium ions at different plume angles and different energies are analysed, and the parameters of plume angle and energy with the best separation effect are obtained, which provides parameters for the engineering implementation of the multi-mass beam separation structure. The research results can be applied to the development of some devices, such as the mass separator, the mass spectrum analyser and material purification. At the same time, it has certain reference significance for the related field's research of the special configuration electromagnetic field controlling multi-mass beam flow.
