This proposal requests support for a university-based Accelerator Research and Development (R&D) program aimed particularly at a future International Linear Collider (ILC). At the start of the millenium, the world's particle physicists arrived at a consensus that an ILC should be the next major facility for high-energy physics. Since then, candidate technologies for the accelerator were developed, the global community has agreed on the technology to be used and a global center to coordinate the completion of the design is now forming. Realizing the vision of the ILC will be a great challenge both technically and in timeliness. The technical challenges lie in both detector and accelerator areas and derive from the need for high luminosity and high precision of measurement. The timeliness challenge lies in the need to have significant overlap with the Large Hadron Collider (LHC) if the full synergy of the two approaches to the energy frontier is to be achieved. The physics goals of the ILC require a starting center-of-mass energy of 500 GeV, upgradeable to approximately 1 TeV or more, and a luminosity that is an ambitious four orders of magnitude larger than that achieved by the Stanford Linear Collider. Achieving the high energy and ultra-low emittance of the ILC requires significant new advances in many areas of accelerator physics and technology, including beam simulation, beam diagnostics, radio-frequency structure development, and accelerator controls. 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. In order to provide governments with a convincing design and cost estimate, in time for substantial overlap with the LHC, these accelerator challenges need to be addressed urgently. This proposal seeks to be a visible step towards that goal.This program will have scientific impact beyond the ILC. The accelerator physics R&D will push the state of the art in many areas (such as diagnostics) that have applications across the whole spectrum of accelerators. Benefits will accrue to the many other fields such as materials science, condensed matter physics, biophysics, and medical science, which utilize accelerators as their front-line research tools. The collaborating groups have a strong history of outreach to undergraduates and K-12 students and teachers. The work supported by this proposal will be integrated into these outreach efforts.

该提案要求支持以大学为基础的加速器研究与开发（R&amp；D）计划，特别是针对未来的国际线性对撞机（ILC）。在千禧年之初，世界上的粒子物理学家达成了一个共识，即ILC应该是高能物理的下一个主要设施。从那时起，加速器的候选技术被开发出来，全球社会已经同意使用的技术，一个协调完成设计的全球中心正在形成。实现国际法委员会的设想在技术上和及时性上都将是一个巨大的挑战。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。及时性的挑战在于，如果要实现两种方法在能量前沿的充分协同作用，就需要与大型强子对撞机（LHC）有很大的重叠。ILC的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（Stanford Linear Collider）达到的亮度大4个数量级。实现ILC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，包括束流模拟、束流诊断、射频结构开发和加速器控制。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。为了及时向政府提供令人信服的设计和成本估算，以便与大型强子对撞机进行大量重叠，这些加速器挑战需要紧急解决。这项建议力求成为实现这一目标的明显步骤。这个项目的科学影响将超越ILC。加速器物理研发将推动许多领域（如诊断）的最新技术，这些领域在整个加速器范围内都有应用。利用加速器作为前沿研究工具的许多其他领域，如材料科学、凝聚态物理、生物物理学和医学，也将从中受益。这些合作团体在向本科生和K-12学生和教师拓展服务方面有着悠久的历史。这项建议所支持的工作将纳入这些外联工作。
