Toutatis, the Cea-Saclay RFQ code
摘要：
连续波高功率直线加速器只有在极低的粒子损耗和极低的结构活化下才能工作。在低能量下，超导体是对损耗非常敏感的元件。为了设计这种激光器，需要对束流动力学有很好的理解。一般情况下，参考代码PARMTEQM是足够的加速器的设计。TOUTATIS的目标是交叉检查结果并获得更可靠的动态。本文介绍了不同的数值方法中使用的代码。它是基于时间的，使用多重网格方法和自适应网格的精细描述的力量，而不是耗时。通过Poisson求解器精确计算磁场，并对叶片进行充分描述，从而可以正确模拟耦合间隙和RFQs末端。显示与PARMTEQM和LIDOS.RFQ的差异。
英文摘要：
A CW high power linear accelerator can only work with very low particles losses and structure activation. At low energy, the RFQ is a very sensitive element to losses. To design the RFQ, a good understanding of the beam dynamics is requested. Generally, the reference code PARMTEQM is enough to design the accelerator. TOUTATIS has been written with goals of cross-checking results and obtaining a more reliable dynamics. This paper relates the different numerical methods used in the code. It is time-based, using multigrids methods and adaptive mesh for a fine description of the forces without being time consuming. The field is accurately calculated through a Poisson solver and the vanes are fully described, allowing to properly simulate the coupling gaps and RFQs extremities. Differences with PARMTEQM and LIDOS.RFQ are shown.
