论文摘要
在中国散布中子源的快速循环同步器中，对注射系统的设计方案采用了反相关的绘画。在横梁调试中，随着抗相关绘画的优化，注射束的损失得到了很好的控制，并且注射效率已超过99％。与调整的其他方面相结合，目标上的光束功率平稳地达到了50 kW。在本文中，我们研究了光束调试中的注射优化。与设计方案的仿真结果相比，横梁分布，横向耦合效果和抗相关绘画的光束损失在梁调试中有所不同。通过机器研究，我们仔细分析了这些差异并研究了它们的原因。
In the rapid cycling synchrotron of the China Spallation Neutron Source, the anti-correlated painting was adopted for the design scheme of the injection system. In the beam commissioning, with the optimization of the anti-correlated painting,the injection beam loss has been well controlled and the injection efficiency has exceeded 99%. Combined with other aspects of adjustments, the beam power on the target has reached 50 kW smoothly. In this paper, we have studied the injection optimization in the beam commissioning. Compared to the simulation results of the design scheme, the transverse beam distribution, transverse coupling effect and beam loss of the anti-correlated painting in the beam commissioning are somewhat different. Through the machine studies, we have carefully analyzed these differences and studied their reasons.
