Abstract

Abstract

The theory of periodic permanent magnetic focusing system was studied. 2-D software UESTC_PPM was implemented. It focuses on axisymmetric models and uses finite differential method(FDM) to compute the magnetic displacement. The one magnetic ring model and the one period model were simulated. The results were compared with the results of Ansoft Maxwell 3D. The magnetic induction intensity curve at axis of symmetry and the absolute value of magnetic induction intensity displacement at axial plane of symmetry that were computed with two kind of software are consistent with each other. UESTC_PPM is useful and accurate.
