Collaborative Research: Demonstration of the Electrical and Mechanical Stability of a BPM-Based Energy Spectrometer for the ILC

这项提议将为未来轻子对撞机探测器，特别是国际大型探测器(ILD)探测器概念所需的研发提供资金。研发项目将解决与ILD概念和相关束流仪器设计相关的关键问题。未来的轻子对撞机预计将是一个前沿科学设备，在高达约1TeV的能量尺度上探索电子和正电子的相互作用。为了充分利用这种加速器的物理机会，必须设计一种具有前所未有的粒度、稳健性和精度的粒子物理探测器，并证明其可行性。ILD基于粒子流，这是一种旨在重建单个粒子的范例，使用高度稳健的跟踪系统，以时间投影室为中心，辅之以硅跟踪，以及适用于分离单个能量沉积的高粒度“相机式”电磁和强子量热仪。粒子流量热仪提供了一种令人兴奋的新方法，以实现新物理所需的显著更好的能量分辨率。如果被证明是有效的，它们可能对未来在高能和核物理实验中的许多应用有用。该提案将支持使用测试束数据开发和验证粒子流算法。探测器项目涉及与推进ILD探测器设计有关的补充方面，其项目侧重于跟踪、热量测量以及束流仪器。这项建议将支持低质量TPC端板和光度监测系统的发展。该提案将产生更广泛的影响，因为许多研发项目使用了大量的本科生，他们高度融入了计划中的研究。大学团体在鼓励代表性不足的团体参与其研究方面有着良好的记录，这一点将继续得到强调。许多探测器研发项目有可能在医学成像等领域带来应用，并将培养一批在实验和探测器技术方面接受过良好培训的科学家。

This proposal will fund the R&D needed for future lepton collider detector and in particular the International Large Detector (ILD) detector concept. The R&D projects will address critical issues related to the design of the ILD concept and associated beam instrumentation. The future lepton collider is expected to be a frontier scientific facility, exploring the interactions of electrons and positrons at energy scales of up to about 1 TeV. To fully exploit the physics opportunities of such an accelerator, it is essential to design a particle physics detector of unprecedented granularity, robustness and precision, and demonstrate that its feasibility. ILD is based around particle flow, a paradigm which aims for reconstruction of individual particles, using a highly robust tracking system centered on a time projection chamber supplemented with silicon tracking, and high granularity "camera-like" electro-magnetic and hadronic calorimetry suited to separation of individual energy deposits. Particle Flow calorimeters offer an exciting new approach to achieve significant better energy resolution needed by the new physics. If proven to work they could be useful for many future applications in High energy and Nuclear Physics experiments. This proposal will support the development and validation of Particle Flow Algorithms using test beam data. The detector projects address complementary aspects associated with advancing the design of the ILD detector with projects focused on tracking, calorimetry as well as beam instrumentation. This proposal will support the development of Low mass TPC endplates and luminosity monitoring system. The proposal will have broader impact in that a number of the R&D projects utilize a significant numbers of undergraduate students who are highly integrated into the planned research. The university groups have a strong track record of encouraging the participation of under-represented groups in their research and this will continue to be emphasized. Many of the detector R&D projects have potential to lead to applications in areas such as medical imaging, and will lead to a cadre of scientists well trained in the art of experimentation and detector technologies.
