Support of the Cornell Electron Storage Ring (CESR) Facility

该提案是支持康奈尔电子储存环（CESR）和CLEO探测器在未来五年内运行的请求。 由于新的B工厂，斯坦福大学的PEP-II和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，这是一个建议，它是要改变CESR，使其在每束1.5到5.6 GeV的能量范围内运行，以便为CLEO提供获得独特的和重要的物理学的途径，并解决CESR的一些最初的目标。CLEO程序在某种程度上是PEP和KEK机器的补充。除了粒子物理计划外，还建议继续为未来提供加速器科学和技术的有力计划。康奈尔大学小组建议在康奈尔高能同步加速器源继续进行一项强有力的X射线科学计划，该计划使用CESR光束的同步辐射，自CESR成立以来一直与粒子物理同时运作。 本文所述方案将于2006年完成。到那时，将停止使用CESR进行粒子物理学研究，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设施的运行，支持CLEO合作者的基础设施，包括实验室计算设施的运行，由CLEO合作的康奈尔部分进行的研究，加速器研发以及相关的教育和推广活动。拟议中的粒子物理学计划包含了原始发现的机会，标准模型独特测试的精确测量，以及在B工厂和日内瓦欧洲核子研究中心的大型强子对撞机上进行数据分析所需的测量。该计划将开始一年的升级1 S，2S和3S共振运行。 然而，对于大多数操作，建议在魅力共振处和附近以及DsDs阈值以上运行。通过利用独特的魅力能量区域的能力，CLEO测量将探索大量的临界弱相互作用和强相互作用现象，将扩展和实现世界范围内的风味物理学，并为掌握非微扰，强相互作用理论奠定基础。这对于全面理解QCD是必不可少的，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，并且将影响强耦合理论出现的粒子物理学之外的许多领域。在此期间，CESR/CLEO计划将作为加速器和探测器研发的重要工具，以支持国家和世界粒子物理计划。由于其巨大的灵活性，CESR是一个很好的实验室，研究非线性的影响参加使用强摇摆磁铁和空间电荷失谐在高密度梁，两个重要的功能阻尼环计划为未来的线性对撞机。此外，他们建议继续研究超导射频加速技术的物理学。作为这项研究的结果，能量回收直线加速器已被提出作为一个超亮的同步辐射源，捕捉世界范围内的关注和兴趣。在常规培养粒子物理和加速器科学的理工科研究生和本科生的基础上，建议增设加速器科学与技术专业学位硕士项目。增加了一名教育外联协调员，以加强他们对当地和内城年轻人的K-12外联。

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.
