Americas Organization for International Linear Collider

这项建议是向国家科学基金会请求部分支持国际直线对撞机(ILC)北美区域主任的活动。ILC的物理目标雄心勃勃，令人信服。近年来，世界已达成共识，认为ILC应该成为高能物理的下一个主要设施。在美国，高能物理咨询小组(HEPAP)将线性对撞机确定为美国基本粒子物理计划的最高优先事项。在国家层面，美国能源部宣布将ILC纳入其新设施20年计划，称其是正在考虑的中期项目中的最优先事项。为了提供一个框架，全世界粒子物理界可以围绕着它来组织其设计和建造ILC的努力，国际未来加速器委员会于2002年成立了国际直线对撞机指导委员会(ILCSC)。去年，ILCSC成立了国际技术推荐小组，成功地为ILC的主直线加速器选择了技术。今年早些时候，ILCSC创建了一个组织来领导机器设计工作的下一步：这个组织被称为全球设计努力(GDE)。GDE将设立一个中央小组和三个区域小组，每个小组分别来自亚洲、欧洲和北美，每个小组由一名区域主任指导。中央小组是ILC项目规划的协调中心。由于这项建议支持实现国际法委员会的一个关键要素，其更广泛的影响是国际法委员会本身。ILC是自然科学领域最令人兴奋的新项目之一。ILC所需的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。利用加速器作为前线研究工具的材料科学、凝聚态物理、生物物理学和医学科学等领域将受益。此外，将提供培训机会，开始解决目前全国加速器物理学家短缺的问题。

This proposal is a request to the NSF for partial support of the activities of the North American Regional Director for the International Linear Collider (ILC). The physics goals of the ILC are ambitious and compelling. In recent years, a world consensus has developed that the ILC should be the next major facility for high-energy physics. Here in the U.S., the High Energy Physics Advisory Panel (HEPAP) identified the linear collider as the highest priority for the U.S. program in elementary particle physics. At the national level, the U.S. Department of Energy announced inclusion of the ILC in its 20-year plan for new facilities, according it the highest priority among the mid-term projects under consideration. To provide a framework around which the worldwide particle physics community can organize its efforts to design and build the ILC, in 2002, the International Committee for Future Accelerators formed the International Linear Collider Steering Committee (ILCSC). Last year, the ILCSC created the International Technology Recommendation Panel, which successfully made the choice of the technology for the main linear accelerator of the ILC. Earlier this year, the ILCSC created an organization to lead the next steps in the design effort for the machine: this organization is called the Global Design Effort (GDE). The GDE will establish a Central Team and three Regional Teams, one each from Asia, Europe, and North America and each one guided by a Regional Director. The Central Team is the focal point for ILC project planning. Since this proposal supports a key element in the realization of the ILC, its broader impact is that of the ILC itself. The ILC is one of the most exciting new projects in the physical sciences. The accelerator physics R&D required for the ILC 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, which utilize accelerators as their front-line research tools. In addition, training opportunities will be provided that can begin to address the current national shortage of accelerator physicists.
