Development and application of cyclotron beam dynamics and multi-physics field simulation technology at CIAE

A great progress on the cyclotron technologies has been achieved at China Institute of Atomic Energy (CIAE) during the 60 years development. A core algorithm research of large-scale parallel computation on beam dynamics in high-current cyclotron based on particle-in-cell (PIC) technology was carried out independently by CIAE and the corresponding codes of CYCPIC2D, CYCPIC3D and OPAL-CYCL for high-current cyclotron were developed with a dedicated high-performance parallel computer cluster PANDA. The development and application of cyclotron beam dynamics and multi-physics field simulation technology at CIAE were mainly introduced in this paper. (authors)
