固定场交替梯度（FFAG）聚焦同步加速器是一种有吸引力的质子驱动器，用于产生强二次粒子，如介子。FFAG同步加速器的磁场是静态的，因此，如果一个有效的高压射频加速系统可用，加速的重复频率可以比普通的快速循环同步加速器（RCS）增加十倍以上，例如1khz。近年来，利用高磁导率磁合金（MA）开发出了一种新型的高梯度宽带射频腔，使FFAG聚焦成为一种很有前景的技术。本文介绍了一种1.5 GeV、10 MW束流功率的质子驱动器的设计。为了在实验上阐明快速循环FFAG同步加速器的可行性，一种原理验证（POP）机器正在开发中，该机器将质子加速到1 MeV，重复频率为1 kHz。
Fixed field alternating gradient (FFAG) focusing synchrotron is attractive as a proton driver for the generation of intense secondary particles such as muons. The magnetic field of the FFAG synchrotron is static, therefore, the repetition rate of acceleration could be increased more than ten times larger, such as 1 kHz, than that of an ordinary rapid cycling synchrotron (RCS) if an efficient high-voltage rf accelerating system becomes available. Recently, a new type of high gradient and broad-band rf cavity using a high-permeability magnetic alloy (MA) has been developed and the FFAG focusing becomes very promising. In this paper, a design of 1.5 GeV and 10 MW beam power of proton driver is presented. In order to clarify the feasibility of rapid cycling FFAG synchrotron experimentally, a proof-of-principle (POP) machine, which accelerates protons up to 1 MeV with 1 kHz repetition, is under development.
