Over the past several decades, particle accelerators have contributed greatly to our understanding of the nature of the universe. Further, their use in research programs world-wide has had a major impact on many sciences. The societal benefits of particle accelerators are especially evident in material science, nuclear medicine, molecular biology and in many other fields. Charged particles or the radiation they produce enable doctors to treat many forms of cancer; an application that is experiencing significant growth. Accelerators are now a major presence in the semiconductor and pharmaceutical industries. As can be seen from the number of advertisements that appear monthly in such Journals as Physics Today and the CERN Courier, there is a dearth of personnel trained in accelerator physics and related technology. The nation's need for advances in the areas mentioned above requires the training of next-generation accelerator physicists, to carry out accelerator R & D on the cutting-edge.One such cutting edge project is based on the interest in using superconducting electron linacs with energy recovery as synchrotron radiation sources. Such energy recovery linacs (ERLs) would open new regimes of X-ray science because they are capable of producing ultra-brilliant X-ray beams, maintaining a very small source size suitable for micro X-ray beams, and making very intense fast X-ray pulses. Each of these characteristics would permit the execution of experiments that are not feasible with existing synchrotron sources. Many technical issues must be satisfactorily resolved before the potential of a full-scale ERL can be realised, including the generation of high average current, high-brightness electron beams; acceleration of these beams to suitable energies without unacceptable emittance degradation; stable and efficient operation of superconducting linear accelerators at very high gradients etc. Cornell University has proposed to resolve these issues by the construction of a prototype ERL. The intention is to then utilize the information that is learned from the prototype to propose the construction of a full-scale ERL light source. The purpose of this interdisciplinary proposal is to construct the first phase of that prototype.

在过去的几十年中，粒子加速器为我们对宇宙本质的理解做出了巨大贡献。此外，它们在全球研究计划中的使用对许多科学产生了重大影响。 粒子加速器的社会益处在材料科学，核医学，分子生物学以及许多其他领域中尤为明显。带电颗粒或产生的辐射使医生能够治疗多种形式的癌症；正在经历显着增长的应用程序。现在，加速器在半导体和制药行业中成为主要的存在。 从当今物理和CERN快递等期刊中每月出现的广告数量可以看出，缺乏接受加速器物理和相关技术的人员。国家对上述领域的进步需求要求对下一代加速器物理学家进行培训，以在尖端进行加速器研发。一个这样的尖端项目是基于对使用超级传导电子linacs换取能量恢复的兴趣，将其作为同步辐射源。这种能量恢复的Linac（ERL）将开放X射线科学的新机制，因为它们能够产生超大型X射线梁，维持适合微型X射线梁的源尺寸，并产生非常强烈的快速X射线脉冲。这些特征中的每一个都允许执行现有同步源不可行的实验。在实现全尺度ERL的潜力之前，必须令人满意地解决许多技术问题，包括产生高平均电流，高亮度电子束；这些梁加速到合适的能量，而不会降解不可接受；超导线性加速器在非常高的梯度等。康奈尔大学提议通过构建原型ERL来解决这些问题。其目的是利用从原型中学到的信息来提出全面的ERL光源的构建。该跨学科建议的目的是构建该原型的第一阶段。
