University-Based Accelerator R&D For A Linear Collider

该提案要求支持一项以大学为基础的物理加速器研发(R&A；D)计划，该计划特别针对未来的直线对撞机(LC)。近年来，世界已达成共识，认为国际液晶应该成为高能物理的下一个主要设施。在国外，欧洲和亚洲社区已经得出了这一结论，而在美国，高能物理顾问小组(HEPAP)将LC确定为美国基本粒子物理计划的最高优先事项。技术挑战存在于探测器和加速器领域，源于对高光度和高测量精度的需求。为了应对这些挑战，19所美国大学联合成立了大学直线对撞机研发联盟(UCLC)，康奈尔大学担任项目经理。物理目标要求初始质心能量为500GeV，可升级到约1TeV或更高，以及雄心勃勃的光度，比斯坦福直线对撞机达到的光度大四个数量级。要实现液晶的高能和超低发射度，需要在加速器物理和技术的许多领域取得重大新进展。这项建议解决了这些领域的主要挑战，利用了经验丰富的加速器科学家和具有仪器专业知识的实验物理学家的才华。这项提议预计会产生一些更广泛的影响。加速器物理研发将在许多领域推动最先进的技术，这些领域的应用遍及整个加速器频谱。受益领域将包括材料科学、凝聚态物理、生物物理学和医学科学。此外，这项提议将提供培训机会，可以开始解决目前全国加速器物理学家短缺的问题。此外，PIS提出了一项新的外展计划，允许教师和学生参与加州大学洛杉矶分校的LC研究工作。这项计划将为高中课堂带来LC将学习的令人兴奋的能量前沿物理的滋味，以及实施该课程所需的最先进技术。

This proposal requests support for a university-based Physics Accelerator Research and Development (R&D) program aimed particularly at a future Linear Collider (LC). In recent years, a world consensus has developed that an international LC should be the next major facility for high energy physics. Abroad, the European and Asian communities have come to this conclusion, and here in the U.S., the High Energy Physics Advisory Panel (HEPAP) identified the LC as the highest priority for the US program in elementary particle physics. The technical challenges lie in both detector and accelerator areas and derive from the need for high luminosity and high precision of measurement. In response to these challenges, nineteen U.S. universities have banded together to form the University Consortium for Linear Collider R&D (UCLC) with Cornell as Project Manager. The physics goals require a starting center-of-mass energy of 500 GeV, upgradeable to approximately 1 TeV or more, and a luminosity of an ambitious four orders of magnitude larger than the luminosity achieved by the Stanford Linear Collider. Achieving the high energy and ultra-low emittance of the LC requires significant new advances in many areas of accelerator physics and technology. This proposal addresses leading challenges in these areas, bringing to bear the talents of both experienced accelerator scientists and experimental physicists with expertise in instrumentation. There are a number of broader impacts to be expected from this proposal. The accelerator physics R&D will push the state of the art in many areas that have applications across the whole spectrum of accelerators. Benefits will accrue to fields such as materials science, condensed matter physics, biophysics, and medical science. In addition, this proposal will provide training opportunities that can begin to address the current national shortage of accelerator physicists. In addition, the PIs propose a new outreach program that will allow teachers and students to join in the LC research work at UCLC universities. This program will bring to high school classrooms a taste of the exciting energy frontier physics to be studied by the LC and the state-of-the-art technologies required for its implementation.
