Description
With the rapid advancement of high-intensity linear accelerators, achieving efficient and accurate design has become a critical challenge in modern accelerator physics. As beam intensity increases, the space charge effect — arising from the mutual repulsion among charged particles within the beam — becomes increasingly significant and must be incorporated into realistic simulations. In this paper, we develop a comprehensive multi-particle simulation program specifically tailored for linear accelerators. The program employs a novel three-dimensional space charge solver based on the tensor decomposition method, which offers both high computational efficiency and numerical accuracy. To validate the proposed program, we apply it to simulate the linear section of the China Spallation Neutron Source (CSNS). The simulation results are systematically compared with those obtained from Tracewin, a well-established beam dynamics code. Good agreement between the two sets of results demonstrates the effectiveness and reliability of our developed simulation program.
