摘要

SIGMAPHI与IN2P3/LPSC合作开发了二维和三维磁性计算工具和方法，用于设计螺旋式FFAG(固定场交替梯度)磁体。这些工具目前被用于RACCAM螺旋缩放FFAG磁体设计。在螺旋间隙形磁体的特殊情况下，为了在加速过程中保持垂直和水平调谐恒定，必须实现仔细的磁性设计。通过对三维场图的跟踪，得到了令人满意的结果，证明了本文提出的水平和垂直调谐方法的有效性。

3-D magnetic calculation methods for spiral scaling FFAG magnet design

2-D and 3-D magnetic calculation tools and methods have been developed at SIGMAPHI, in collaboration with IN2P3/LPSC, to design spiral FFAG (fixed field alternating gradient) magnets. These tools are currently being used for RACCAM spiral scaling FFAG magnet design. In the particular case of a spiral gap shaped magnet, a careful magnetic design has to be realized in order to keep both vertical and horizontal tunes constant during acceleration process. Promising results, obtained from tracking in 3-D field maps, demonstrate the efficiency of the horizontal and vertical tune adjustment methods presented in this paper.
