研究设计了一种用于硼中子俘获治疗(BNCT)的紧凑型固定磁场交变梯度(FFAG)加速器。首先采用FFAG加速器磁铁的线性简化模型,计算确定了加速器的基本结构参数;再用WINAGILE程序进行了磁聚焦结构的设计和优化,得到了Beta函数、色散函数、包络函数及工作点等;采用MAD程序对设计结果进行了复算,并对两种程序的计算结果作了进一步的对比分析;最后采用ZGOUBI程序进行非线性磁场下粒子追踪。FFAG加速器的超周期为6,能量为11 MeV,场指数k为1.9,周长为11.1795 m,结构紧凑。分析结果表明,优化设计的FFAG加速器达到了预期的设计目标。

A compact FFAG accelerator for Boron Neutron Capture Therapy (BNCT) has been designed. Firstly, a linear simplified magnet model has been applied to calculate the basic parameters of FFAG accelerator;Then the WINAGILE program is used to design and optimize the lattice, as well as to obtain the critical parameters such as the Beta functions, the dispersion functions, the envelopes and the tunes; Also, the MAD program is used to check the design scheme; Finally, the ZGOUBI program is used to simulate the particles movement in the nonlinear magnetic field. The super period of the FFAG accelerator is 6. The energy is 11 MeV and the field index k is 1.9. The structure is compact with the circumference of 11.179 5 m. The results show that this optimized design has achieved the proposal object.
