Abstract
In this paper, the dual-ring double scattering method of proton beam spreading, such as the relation of beam distribution function with beam uniformity and beam efficiency, the effection of beam misalignment, the variation of beam along longitudinal direction are studied. The depths of dual-ring double scatterers corresponding to different beam field are calculated. Liquor scatterer instead of solid one is proposed.
