It is generally believed that the LHC will discover new physics at the TeV scale that can shed light on the origin of electroweak symmetry breaking, and that could indicate new phenomena beyond the Standard Model of particle physics. It is also expected that in order to understand the physical origin of this new physics, a TeV scale lepton collider will be needed. The International Linear Collider (ILC) is the most well developed candidate for the next lepton collider. The current ILC R&D directed by the Global Design Effort (GDE), working under the International Linear Collider Steering Committee (ILCSC), will present a technical design report in 2012. The Linear Collider Steering Group of the Americas (LCSGA) was established to provide guidance to funding agencies in the U.S. and Canada, and to articulate the Americas' stance on linear colliders within the ILCSC. An important aspect of the LCSGA activities in the coming two years is establishing the goals and organization for linear collider work in the period between the end of GDE and ILCSC and the time when LHC results will be clear and can offer the opportunity to launch a linear collider project. In early 2011, the PI of this proposal became the chair of LCSGA. This award provides funds for a portion of the PI's salary and travel funds to cover the expected travel associated with LCSGA activities. The intellectual merit will reside in finding a mechanism by which the global community can come together within a framework that allows each nation participating in a linear collider to contribute effectively and derive the benefits of the research it enables. The broader impacts from this proposal will stem from the more fundamental understanding of the forces of nature that can be provided by the linear collider beyond that which can be obtained from existing experimental facilities. Technologies developed for it may be applicable to other fields in science and engineering. Finding the organizational mechanisms by which a linear collider could be realized will be critical.

人们普遍认为，大型强子对撞机将在TeV尺度上发现新的物理，可以揭示电弱对称破缺的起源，这可能表明粒子物理标准模型之外的新现象。预计为了了解这一新物理的物理起源，将需要一台TeV尺度的轻子对撞机。国际直线对撞机(ILC)是下一代轻子对撞机最成熟的候选者。目前由国际直线对撞机指导委员会(ILCSC)领导的国际直线对撞机研发中心将在2012年提交一份技术设计报告。美洲直线对撞机指导小组(LCSGA)的成立是为了向美国和加拿大的资助机构提供指导，并在ILCSC内阐明美洲对直线对撞机的立场。未来两年LCSGA活动的一个重要方面是，确定在GDE和ILCSC结束期间以及大型强子对撞机结果将明确并可提供启动线性对撞机项目的机会期间线性对撞机工作的目标和组织。2011年初，这项提案的私隐专员成为LCSGA主席。这一奖励提供了PI的部分工资和差旅资金，以支付与LCSGA活动相关的预期差旅。智力上的价值将在于找到一种机制，通过这种机制，全球社会可以在一个框架内聚集在一起，使参与线性对撞机的每个国家都能有效地做出贡献，并从它所实现的研究中获得好处。这一提议的更广泛影响将源于对线性对撞机可以提供的自然力的更基本的理解，而不是从现有的实验设施中获得的自然力。为其开发的技术可能适用于科学和工程的其他领域。找到能够实现线性对撞机的组织机制将是至关重要的。
