Multi-Pass Superconducting Energy Recovery Linacs - Accelerator Physics Design for Future Facilities

在这个项目中，学生将研究PERLE，EIC冷却器和UK-XFEL的优化，这些都包含了多通道，循环CW SC直线加速器的各个方面。要解决的加速器物理挑战是找到一个共同的框架，以确定最佳的系统配置，使强大的集体效应（空间电荷，相干和非相干SR，微聚束）的控制可以实现最小的成本。重点将是采取设计过程的成熟状态超越“测试设施”这类机器，在系统架构和设计优化。学生将参与光束线设计，然后构建高保真模拟来预测整体系统性能，并将其与分析和半分析模型相连接。

In this project the student will investigate optimisation of PERLE, EIC Cooler and UK-XFEL which all incorporate aspects of a multi-pass, recirculating CW SC linacs. The accelerator physics challenge to be addressed is finding a common framework to determine optimum system configurations such that robust control of collective effects (space charge, coherent and incoherent SR, microbunching) can be achieved with minimal cost. The emphasis will be on taking the design process to a state of maturity beyond "test facility" for this class of machines, looking at the system architecture and design optimisation. The student will participate in beamline design, then construct high fidelity simulations to predict overall system performance and connect these to analytic and semi-analytic models.
