论文摘要
高强度或高亮度加速器中的非线性空间充电效应可以通过加速器对梁的性质产生重大影响。这些效果包括在加速器设计中，通过自洽多粒子跟踪模拟。为了研究最终梁对加速器设计参数的敏感性，必须多次进行耗时的空间充电模拟。在本文中，我们提出了一个可区分的自搭配空间充电模拟模型，该模型仅通过一个模拟就可以研究光束灵敏度。此类模型也可以与基于梯度的数值优化器一起用于加速器设计优化，包括自洽空间充电效果。
The nonlinear space-charge effects in a high intensity or high brightness accelerator can have a significant impact on the beam properties through the accelerator. These effects are included in the accelerator design via self-consistent multi-particle tracking simulations. In order to study the sensitivity of the final beam's properties with respect to the accelerator design parameters, one has to carry out the time-consuming space-charge simulation multiple times. In this paper, we propose a differentiable self-consistent space-charge simulation model that enables the study of the beam sensitivity through only one simulation. Such a model can also be used with gradient-based numerical optimizers for accelerator design optimizations including the self-consistent space-charge effects.
