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.

该提案要求支持一个以大学为基础的加速器研究和开发（R D）计划，特别是针对未来的国际直线对撞机（ILC）。在千禧年开始时，世界粒子物理学家达成共识，ILC应该是高能物理的下一个主要设施。从那时起，加速器的候选技术已经开发出来，全球社会已经就将要使用的技术达成一致，并且协调设计完成的全球中心正在形成。 实现国际法委员会的远景，无论在技术上还是在及时性上都将是一个巨大的挑战。技术挑战在于探测器和加速器领域，并且来自于对高光度和高测量精度的需求。及时性的挑战在于，如果要实现这两种方法在能源前沿的充分协同作用，就需要与大型强子对撞机（LHC）有显著的重叠。 ILC的物理学目标要求初始质心能量为500 GeV，可达到约1 TeV或更高，亮度比斯坦福大学直线对撞机大四个数量级。 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，使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得以发挥。为了及时为政府提供令人信服的设计和成本估算，以便与LHC进行大量重叠，这些加速器挑战需要紧急解决。这项建议旨在成为实现这一目标的一个明显步骤。该计划将产生超越国际法委员会的科学影响。加速器物理学研发将推动许多领域（如诊断）的最新技术，这些领域的应用遍及整个加速器领域。许多其他领域，如材料科学，凝聚态物理学，生物物理学和医学科学，将加速器作为其前沿研究工具，将从中受益。 合作小组有一个强大的外展本科生和K-12学生和教师的历史。本提案所支持的工作将纳入这些外联工作。
