Support of the Cornell Electron Storage Ring (CESR) Facility

这项提议是为了支持康奈尔电子储存环(CESR)和CLEO探测器在未来五年的运作。由于新的B工厂，斯坦福的PEP-II和KEK的日本国家加速器研究实验室的KEK-B，现在的亮度通常超过CESR，这是一项建议，改变CESR，使其在每束1.5到5.6GeV的能量范围内运行，使CLEO能够接触到独特和重要的物理，并以补充PEP和KEK机器的方式解决CESR/CLEO计划的一些原始目标。除了粒子物理计划外，还建议在未来继续开展一项充满活力的加速器科学和技术计划。康奈尔大学小组提议在康奈尔高能同步加速器源继续开展一项强大的X射线科学计划，该计划使用来自CESR光束的同步辐射，自CESR开始以来一直与粒子物理同步运行。本文所述的方案将于2006年完成。到那时，停止将CESR用于粒子物理将是适当的，并将其主要用于X射线科学和一些加速器研发测量。所需资金主要用于支持CESR设施的运营，支持CLEO合作者的基础设施，包括实验室计算设施的运营，CLEO协作的康奈尔部分的研究，加速器研发，以及相关的教育和推广活动。拟议的粒子物理计划包括原创发现的机会，标准模型独特测试的精确测量，以及使B工厂和日内瓦欧洲核子研究中心的大型强子对撞机进行数据分析所需的测量成为可能。该计划将以一年的Upsilon 1S、2S和3S共振运行开始。然而，对于大多数操作，建议运行在魅力共振和高于DSDS阈值的水平和附近。通过利用魅力能量区独有的能力，CLEO测量将探索一大组关键的弱相互作用和强相互作用现象，将在世界范围内推广和实现风味物理，并将为掌握非微扰、强相互作用理论奠定基础。这对于全面理解QCD是至关重要的，对于理解下一代前沿加速器揭示的新理论很可能是至关重要的，并将影响到粒子物理学以外的许多领域，这些领域出现了强耦合理论。在此期间，CESR/CLEO计划将成为加速器和探测器研发的重要载体，以支持未来的国家和世界粒子物理计划。由于其极大的灵活性，CESR是研究强摇摆磁铁和高密度束流中空间电荷失谐引起的非线性影响的极佳实验室，这两个重要特征都是计划用于未来线性对撞机的阻尼环。此外，他们还建议继续在超导射频加速技术的物理学方面进行研发。作为这一研发的结果，能量回收直线加速器已被提出为同步辐射的超亮光源，吸引了全世界的关注和兴趣。在他们对理工科毕业生和粒子物理和加速器科学本科生的常规培训之外，他们建议增加加速器科学和技术的专业学位硕士课程。增加了一名教育外展协调员，以加强他们对当地和市中心年轻人的K-12外展。

This proposal is a request to support the operation of the Cornell Electron Storage Ring (CESR) and the CLEO detector for the next five years. Since the new B-Factories, PEP-II at Stanford and KEK-B at the Japanese National Laboratory for Accelerator Research, KEK, now have luminosities routinely exceeding that of CESR, this is a proposal to alter CESR for operation over the energy range 1.5 to 5.6 GeV per beam to provide CLEO with access to unique and important physics and to address some of the original goals of the CESR/CLEO program in a way complementary to the PEP and KEK machines. In addition to the particle physics program, it is proposed to continue a vigorous program of accelerator science and technology for the future. The Cornell University group proposes to continue a strong program in x-ray science at the Cornell High Energy Synchrotron Source that, using synchrotron radiation from the CESR beams, has operated simultaneously with particle physics since the inception of CESR. The program described herein will be complete in 2006. At that time it will be appropriate to cease using CESR for particle physics and to devote it largely to x-ray science and to some accelerator R&D measurements.The funds are requested primarily to support operation of the CESR facility, support infrastructure for CLEO collaborators including operation of the laboratory computing facility, research by the Cornell portion of the CLEO collaboration, accelerator R&D, and related educational and outreach activities. The proposed particle physics program contains opportunities for original discovery, precision measurements for unique tests of the Standard Model and enabling measurements that will be necessary for analyzing data to be taken at the B-factories and the Large Hadron Collider at CERN, Geneva. The program will begin with a year of Upsilon 1S, 2S and 3S resonance running. For the majority of the operation, however, it is proposed to run at and near the charm resonances and above DsDs threshold. By exploiting capabilities that are unique to the charm energy region, CLEO measurements will explore a large set of critical weak and strong interaction phenomena, will extend and enable flavor physics worldwide and will lay the foundation for mastery of a non-perturbative, strongly interacting theory. This is essential for a full understanding of QCD, will quite likely be crucial for understanding new theories revealed by the next generation of frontier accelerators and will impact many fields beyond particle physics where strongly-coupled theories arise. During this period, the CESR/CLEO program will serve as an important vehicle for accelerator and detector R&D in support of the national and world particle physics programs to come. Because of its great flexibility, CESR is an excellent laboratory for studying the effects of non-linearities attending the use of strong wiggler magnets and space charge detuning in high-density beams, both important features of the damping rings planned for future linear colliders. Additionally, they propose continued R&D in the physics of superconducting radio frequency acceleration techniques. As a result of this R&D, the Energy Recovery Linac has been put forward as an ultra bright source of synchrotron radiation, capturing worldwide attention and interest. To their routine training of science and engineering graduates and undergraduates in particle physics and accelerator science, they propose to add a professional degree MS program in accelerator science and technology. An education outreach coordinator has been added to enhance their K-12 outreach to local and inner city young people.
