摘 要：This paper presents the research progress in the beam dynamics problems for future high intensity compact cyclotrons by utilizing the state-of-the-art high performance computation technology.A Start-to-Stop model,which includes both the interaction of the internal particles of a single bunch and the mutual interaction of neighboring multiple bunches in the radial direction, is established for compact cyclotrons with multi-turn *** model is then implemented in OPAL-CYCL,which is a 3D object-oriented parallel code for large scale particle simulations in *** addition,to meet the running requirement of parallel computation,we have constructed a small scale HPC cluster system and tested its ***,the high intensity beam dynamics problems in the 100 MeV compact cyclotron,which is being constructed at CIAE,are studied using this code and some conclusions are drawn.
