THE CHARGE DEPOSITION IN THE NUMERICAL SIMULATION OF HIGH-CURRENT BEAM

A new method of charge deposition of high-current beam, conservation-mapmethod, is given. The advantages of Neil's and other various methods areadopted. The mistake of Neil's method and the limitation of other variousmethods is discarded. so the method is accurate without additional assumption.The method not only applies to the case of steady laminar flow but also appliesto the case of steady non-laminar flow.
