University-Based Detector Research and Development for the International Linear Collider

在本世纪初，世界上的粒子物理学家达成共识，认为国际直线对撞机(ILC)应该成为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，全球社区已经就要使用的技术达成一致，一个协调完成设计的全球中心现在正在形成。实现国际法委员会的愿景无论在技术上还是在及时性上都将是一个巨大的挑战。技术挑战存在于探测器和加速器领域，源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)有重大重叠。ILC的探测器具有很高的挑战性。这一点并不总是被完全理解。虽然大型强子对撞机实验需要在探测器技术方面取得许多进展，但ILC实验必须解决不同的挑战。为了应对这些技术挑战，需要在未来几年内制定探测器的概念设计。这项提案旨在朝着这一目标迈出重要的一步。它包括许多不同的大学团体和实验室将要开展的一些项目。这些项目涉及探测器要求的关键方面，包括为所有探测器子系统开发重要技术以及评估它们所需的软件。国际集团现在正在围绕几个探测器概念联合起来，大多数项目都直接适用于其中一个或多个。对国际法委员会至关重要的是，美国调查人员与他们在国外的同事之间有密切的沟通，这一计划将产生超出国际法委员会的科学影响。探测器的研发将在许多技术战线上带来进步。为在线性对撞机的低辐射环境中进行精确测量而优化的探测器技术将在高能物理的其他领域以及其他领域得到应用。这些合作团体在接触本科生、K-12学生和教师方面有着很强的历史。这项提议所支持的工作将纳入这些外联工作。

At the start of the millenium, the world's particle physicists arrived at a consensus that an International Linear Collider (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 detectors for the ILC are highly challenging. This is not always fully appreciated. While many advances in detector technology were required for the LHC experiments, different challenges must be addressed for the ILC experiments. To meet these technical challenges will require the development of conceptual designs for the detectors in the next few years.This proposal seeks to take an important step towards that goal. It includes a number of projects to be carried out by many diverse university groups and laboratories. The projects address key aspects of the detector requirements, including the development of important technologies for all the detector subsystems and the software needed to evaluate them. International groups are now coalescing around several detector concepts, and most of the projects are directly applicable to one or more of these. As is essential for the ILC, there is close communication between the US investigators and their colleagues abroad.This program will have scientific impact beyond the ILC. The detector R&D will lead to advances in a number of technical fronts. Detector technologies optimized to perform precision measurements in the low-radiation environment of a linear collider will have applications in other areas of high energy physics, as well as in other fields. 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.
