University-Based Accelerator R&D For A Linear Collider

该提案要求支持一个以大学为基础的物理加速器研究和开发（R&amp；D）计划，特别是针对未来的线性对撞机（LC）。近年来，世界上已经形成了一个共识，即国际LC应该是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个结论，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项目的最高优先级。技术上的挑战既存在于探测器领域，也存在于加速器领域，并且源于对高亮度和高精度测量的需求。为了应对这些挑战，19所美国大学联合起来成立了线性对撞机研发大学联盟（UCLC），康奈尔大学担任项目经理。物理目标要求起始质心能量为500 GeV，可升级到大约1 TeV或更高，并且亮度要比斯坦福线性对撞机所达到的亮度大4个数量级。实现LC的高能量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的新进展。该提案解决了这些领域的主要挑战，带来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能。这一提议预计会产生一些更广泛的影响。加速器物理研发将推动许多领域的最新技术，这些领域在整个加速器范围内都有应用。材料科学、凝聚态物理、生物物理学和医学等领域将从中受益。此外，该提案将提供培训机会，可以开始解决目前国家加速器物理学家短缺的问题。此外，pi还提出了一项新的外展计划，允许教师和学生加入UCLC各大学的LC研究工作。这个项目将给高中教室带来令人兴奋的能量前沿物理学的味道，由LC研究和实施所需的最先进的技术。

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.
