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.

建议开展一种新的用于低发射度电子束产生超亮同步辐射的粒子加速器复合体的研究。主要的研究将集中在高能电子束存储环的设计上，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。研究的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度相对论电子束的稳定解。长期目标是在同步辐射光谱的x射线部分产生具有衍射限制的源尺寸的电子束。这样的低发射度存储环将需要新的方法将粒子注入其中，因此这项研究计划的第二个方面是设计紧凑的低发射度电子直线加速器。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)本身产生辐射。该计划不仅要创建一个物理模型；研究还必须集中在一个有用的参数空间，该参数空间符合加拿大同步加速器光用户社区的要求，并且在成本和工程意义上是实际可实现的。最终目标是为将连接到加速器的X射线光束线实现衍射限制的源尺寸。这项研究的预期结果是完成了同步辐射光源的电子源、注入系统和储存环的设计，可以用来取代现有的CLS设施。它将为加拿大同步加速器用户群体提供一个解决方案，他们要求更明亮、更连贯的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HQP的传统，这些HQP将负责建造、调试和操作未来的光源。由于构建光源是一代人一次的事件，大多数HQP不会从体验这种体验中获益。取而代之的是，我将利用我广泛的全球协作者网络，让参与该计划的总部能够访问世界各地的加速器设施，以获得目前正在制造和调试的机器的经验。特别是，我将利用我在萨斯喀彻温省大学和世界上最大的加速器实验室欧洲核子研究组织(CERN)之间达成的协议，在瑞士提供高能物理加速器研究项目的培训和经验。作为加速器物理界会议和学校委员会的成员，我将确保学生们获得最好的研究环境，让他们成长并接触到许多国际专家。
