It is proposed to conduct research into a new particle accelerator complex for low emittance electron beams to generate ultra brilliant synchrotron radiation. The main research will focus is on a high energy electron beam storage ring design, which will use the latest design principles combined with modern computing power to optimise the performance of the ring. The research challenge is to find stable solutions for low emittance relativistic electron beams in a non-linear electromagnetic lattice, made up of magnets and high power radio frequency acceleration cavities. The long term goal is to create electron beams with diffraction limited source sizes in the x-ray part of the synchrotron radiation spectrum. Such low emittance storage rings will require new methods of injecting particles into them, so a second aspect of this research program is to design compact low emittance electron linear accelerators. In this instance, the trend is for high energy linear accelerators to act both as an injector for a storage ring and as a Free Electron Laser (FEL) to generate radiation themselves. This program is not only to create a physical model; the research must also concentrate on a useful parameter space that fits the demands of the Canadian synchrotron light user community and be practically realisable in a cost and in an engineering sense. The ultimate goal is to achieve a diffraction limited source size for the x-ray beamlines that will be attached to the accelerator. The expected outcome from this research is the complete design of an electron source, injection system and storage ring for a synchrotron light source that can be used to replace the present CLS facility. It will provide a solution for the Canadian synchrotron user community who are demanding brighter and more coherent sources of x-rays to support their future research needs.In the process of conducting the research, this program will continue the physics department's tradition of training the next generation of HQPs who will be responsible for building, commissioning and operating the future light source. Since building a light source is a once in a generation occurrence, most HQPs do not get the benefit of experiencing this. Instead, I will use my extensive global network of collaborators to give HQPs in this program access to accelerator facilities world wide to gain experience on machines that are currently being built and commissioned. In particular, I will use the agreement I have created between the University of Saskatchewan and the world's largest accelerator laboratory the European Organisation for Nuclear Research or CERN to provide training and experience working on accelerator research projects in high energy physics in Switzerland. As a committee member for conferences and schools in the accelerator physics community, I will ensure students will get the best research environment for them to grow and access to many international experts.

建议研究一种新型粒子加速器复合体，用于低发射电子束产生超亮同步加速器辐射。主要研究将集中在高能电子束存储环设计上，它将利用最新的设计原理结合现代计算能力来优化环的性能。研究挑战是在由磁铁和高功率射频加速腔组成的非线性电磁晶格中找到低发射率相对论电子束的稳定解决方案。长期目标是在同步加速器辐射光谱的 X 射线部分产生具有衍射限制源尺寸的电子束。这种低发射率存储环需要新的方法将粒子注入其中，因此该研究计划的第二个方面是设计紧凑的低发射率电子线性加速器。在这种情况下，高能直线加速器的趋势是既充当存储环的注入器，又充当自由电子激光器（FEL）以自身产生辐射。这个程序不仅仅是创建一个物理模型；该研究还必须集中于一个有用的参数空间，该空间符合加拿大同步加速器光用户社区的需求，并且在成本和工程意义上可以实际实现。最终目标是为连接到加速器的 X 射线束线实现衍射限制源尺寸。这项研究的预期成果是同步加速器光源的电子源、注入系统和存储环的完整设计，可用于取代现有的 CLS 设施。它将为加拿大同步加速器用户群体提供解决方案，他们需要更亮、更相干的 X 射线源来支持他们未来的研究需求。在进行研究的过程中，该计划将延续物理系培训下一代的传统。一代总部人员将负责建造、调试和运营未来的光源。由于建造光源是一代人才会遇到的事情，因此大多数 HQP 都没有从经历这一过程中受益。相反，我将利用我广泛的全球合作者网络，让该计划中的总部能够访问世界各地的加速器设施，以获得当前正在建造和调试的机器的经验。特别是，我将利用萨斯喀彻温大学与世界上最大的加速器实验室欧洲核研究组织（CERN）之间达成的协议，为瑞士高能物理加速器研究项目提供培训和经验。作为加速器物理界会议和学校的委员会成员，我将确保学生获得最好的研究环境，让他们成长并接触许多国际专家。
