A proposal for the programme of the John Adams Institute for Accelerator Science 2021-2025

约翰亚当斯加速器科学研究所（JAI）是先进加速器科学和技术的卓越中心。我们进行研发和培训，提供专业知识，并促进加速器在科学和社会中的应用。JAI目前包括20名教师，23名工作人员和38名来自牛津大学（UOXF），伦敦皇家霍洛威大学（RHUL）和伦敦帝国理工学院（ICL）物理系的博士生。来自英国国家实验室和CERN的另外33名工作人员隶属于我们的研究和教学计划。我们有六个指导原则：a）开发，支持和参与对英国具有战略重要性的加速器科学设施和研发计划; B）发展全球合作，提高我们的能力;c）开发新型加速和紧凑光源技术及其应用;d）提供世界领先的培训计划，以培养该领域的下一代领导者; e）向公众和决策者通报该领域的发展情况;f）加强伙伴大学之间的联系，以提供一个大于各部分总和的方案。在2021-2025年期间，我们专注于对国家优先事项最有利的研究领域：低发射度、高亮度电子束，包括下一代电子-正电子对撞机（ILC，CLIC），钻石光源（DLS）及其升级，以及未来的英国自由电子激光。高能/高强度强子束，包括当前和未来的能源前沿质子对撞机（LHC，HL-LHC，FCC）和ISIS及其升级。先进的加速技术，包括激光和束驱动的等离子体尾场加速。使用电子、质子和离子束的粒子束治疗应用。通过这个项目，我们通过在我们的国内和海外设施中发挥主导作用来支持英国的加速器战略，包括：STFC/RAL的DLS、ISIS和CLF，STFC/DL的CRAMA，CERN的LHC、HL-LHC、CLIC、FCC和AWAKE，DESY的FLASHforward，KEK的ATF/ATF 2。这些主题使我们能够最佳地支持我们的核心目标，即支持主要的国家和国际加速器开发;激励我们的研究人员，并给予他们最先进的技术技能;并能够将我们的知识转移到主要的合作开发和行业。

The John Adams Institute for Accelerator Science (JAI) is a centre of excellence for advanced accelerator science and technology. We perform R&D and training, provide expertise, and promote accelerator applications in science and society. The JAI currently comprises 20 faculty, 23 staff, and 38 PhD students from the Physics Departments of Oxford University (UOXF), Royal Holloway University of London (RHUL), and Imperial College London (ICL). An additional 33 staff from the UK's national laboratories and CERN are affiliated with our research and teaching programmes. We have six guiding principles: a) Develop, support and engagement of accelerator science facilities and R&D programmes of strategic importance for the UK; b) Develop worldwide collaborations that enhance the capabilities available to us;c) Develop novel acceleration and compact light source techniques and their applications;d) Deliver a world leading training programme to develop the next generation of leaders in the field;e) Communicate developments in the field to the public and decision makers;f) Strengthen the links among the partner universities to deliver a programme that is greater than the sum of its parts. For the period 2021-2025, we have focused on research areas that have the greatest benefit to national priorities: Low-emittance, high-brightness electron beams, including next-generation electron-positron colliders (ILC, CLIC), the Diamond Light Source (DLS) and its upgrade, and a future UK FEL.High-energy/high-intensity hadron beams, including current and future energy-frontier proton colliders (LHC, HL-LHC, FCC), and ISIS and its upgrade.Advanced acceleration techniques, including laser- and beam-driven plasma-wakefield acceleration.Particle-beam therapy applications using electron, proton and ion beams.Through this programme we are supporting the UK's accelerator strategy by taking lead roles in both our national and overseas facilities including: DLS, ISIS and CLF at STFC/RAL, CLARA at STFC/DL, LHC, HL-LHC, CLIC, FCC and AWAKE at CERN, FLASHforward at DESY, and ATF/ATF2 at KEK.These themes position us optimally to support our core goals of supporting major national and international accelerator developments; motivating our researchers and giving them skills in state-of-the-art technologies; and being able to transfer our knowledge to major collaborative developments and to industry.
