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.

建议对低发射器电子梁进行新的粒子加速器复合物进行研究，以产生超亮的同步辐射。主要的研究将重点放在高能电子束存储环设计上，该设计将使用最新的设计原理与现代计算能力相结合来优化环的性能。研究挑战是在非线性电磁晶格中找到低发射相对论电子束的稳定解决方案，该晶石由磁铁和高功率射频加速型腔腔组成。长期目标是在同步加速器辐射谱的X射线部分中创建具有衍射有限​​源尺寸的电子束。如此低的发射量存储环将需要将颗粒注入其中的新方法，因此该研究程序的第二个方面是设计紧凑的低排放电子线性加速器。在这种情况下，高能线性加速器的趋势既可以充当存储环的喷油器，又是自由电子激光器（FEL），以生成辐射本身。该程序不仅是创建一个物理模型；该研究还必须集中于有用的参数空间，该空间适合加拿大同步灯光用户社区的需求，并且在工程意义上实际上可以实现。最终目标是实现将附加到加速器的X射线梁的衍射有限源大小。这项研究的预期结果是可用于更换当前CLS设施的同步子源的电子源，注入系统和存储环的完整设计。它将为加拿大同步器用户社区提供解决方案，他们要求更明亮，更连贯的X射线来源以支持其未来的研究需求。在进行研究的过程中，该计划将继续培训物理部门的传统，培训下一代HQP，他们将负责建筑，调试和运营未来的光源。由于构建光源是一代人的一次，因此大多数HQP都无法获得经历。取而代之的是，我将使用我广泛的全球合作者网络在该计划中访问全球加速器设施的HQP，以获得当前正在构建和调试的机器的经验。特别是，我将使用我在萨斯喀彻温大学和世界上最大的加速器实验室之间建立的协议，欧洲核研究或CERN组织提供培训和经验，从事瑞士高能物理学加速器研究项目的培训和经验。作为加速器物理社区中会议和学校的委员会成员，我将确保学生将获得最佳的研究环境，使他们成长并获得许多国际专家。
