The beam dynamics study for the CYCIAE-100 cyclotron

摘要

A new RIB project, Beijing Radioactive Ion-beam Facility (BRIF), has been started at CIAE since 2004. For this project, a 100 MeV high intensity compact cyclotron, CYCIAE-100, is selected as the driving accelerator for radioactive ion beam production. The cyclotron will provide the proton beam of 75-100 MeV with an intensity of 200-500 μA. The features of the cyclotron have already been described in several papers published elsewhere. In this paper the beam dynamics study is reviewed systematically. The basic parameters and numerical calculations results on the static orbit and accelerated orbit are given. The space charge effects, including the mutual interaction of neighboring multiple bunches in the radial direction, are studied with OPAL-CYCL code, and the current limit determined by space charge effects for this machine is predicted by fully 3D simulation.
