快循环同步加速器（RCS）是中国空间中子源（CSNS）的关键部件。空间电荷效应是CSNS/RCS中的重要问题之一，它限制了最大束流强度和最大束流功率。空间电荷效应是RCS中发射度增长和束流损失的主要来源。通过对CSNS/RCS的仿真研究了空间电荷效应。通过对喷涂轨迹的优化，得到了最优的喷涂分布。在加速过程中的空间电荷效应进行了研究和危险的共振，这可能会导致发射度增长和束流损失，进行了调查。研究结果对CSNS/RCS的设计和调试具有重要的参考价值。
The Rapid Cycling Synchrotron (RCS) is a key component of the China Spallation Neutron Source (CSNS). The space charge effect is one of the most important issues in the CSNS/RCS, which limits the maximum beam intensity, as well as the maximum beam power. Space charge effects are the main source of emittance growth and beam loss in the RCS. Space charge effects have been studied by simulation for the CSNS/RCS. By optimizing the painting orbit, the optimized painting distribution was obtained. The space charge effects during the acceleration are studied and dangerous resonances, which may induce emittance growth and beam loss, are investigated. The results are an important reference for the design and commissioning of the CSNS/RCS.
