The China Spallation Neutron Source/Rapid Cycling Synchrotron (CSNS/RCS) accelerates a high-intensity proton beam from 80 MeV to 1.6 GeV. Since the beam current and beam power is high, the beam loading is a severe problem for the stability of the circulating beam in the RCS. To study the beam loading effect in the CSNS/RCS theoretically, the RLC circuit model of the rf cavity, the method of Fast Fourier Transform and the method of Laplace transform have been employed to obtain the impedance of the rf system, the beam spectrum and the beam-induced voltage, respectively. Based on these physical models, the beam dynamics equations have been revised and a beam loading model has been constructed in the simulation code ORIENT. By using the code, the beam loading effect on the rf system of the CSNS/RCS has been investigated. Some simulation results have been obtained and conclusions have been drawn. 相似文献

电子云不稳定性是强流质子加速器稳定运行的一个重大障碍。在电子云积累的过程中,二次电子多级倍增是电子云的主要来源。二次电子多级倍增机制可以用电子的运动和能量增益来分析。为了得到电子云的密度及分布,编写了一个模拟程序用来跟踪电子云的发展演化过程。分析了在质子束团作用下电子的运动,分析二次电子多级倍增的原因,并用模拟程序进行了计算,结果发现电子云与束团的纵向分布密切相关。 相似文献
