The impact of particle beam, or accelerator science is extremely broad. Indeed, advances in many branches of science such as the material sciences, nuclear science, elementary particle science, to name but a few, are paced by advances in accelerator science and technology. The science of particle beams is rich and challenging. Particle beams can be considered as many body systems with specified distributions, exhibiting many collective instabilities and self-organizing phenomena when interacting with electromagnetic fields and plasmas. Studies of these transitions from one non-equilibrium state to another, has progressed rapidly in recent years, but much remains to be done. Much of the work in these areas has come to reside in the DOE National Laboratories. There is growing realization that universities have a unique and important role to play and that enhancing the university role will result in significant advances in accelerator science and development and in their broad impact on other sciences. In this proposal, important "physics of beams" research is proposed by a university group, using state-of-the-art equipment and diagnostics. This research has the potential of discovering new, useful, and exciting phenomena.

粒子束或加速器科学的影响极其广泛。事实上，许多科学分支的进步，如材料科学、核科学、基本粒子科学，仅举几例，都是由加速器科学和技术的进步所推动的。粒子束科学内容丰富，具有挑战性。粒子束可以被认为是许多具有特定分布的体系统，在与电磁场和等离子体相互作用时表现出许多集体不稳定性和自组织现象。近年来，对这些从一种非平衡态到另一种非平衡态转变的研究进展迅速，但仍有许多工作要做。这些领域的大部分工作都在美国能源部国家实验室进行。人们越来越认识到，大学可以发挥独特而重要的作用，加强大学的作用将在加速科学和发展方面取得重大进展，并对其他科学产生广泛影响。在这个提案中，一个大学小组提出了重要的“光束物理学”研究，使用最先进的设备和诊断。这项研究有可能发现新的、有用的和令人兴奋的现象。
