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

该提案将资助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。研发项目将解决与ILD概念和相关光束仪器设计相关的关键问题。未来的轻子对撞机有望成为前沿科学设备，探索电子和正电子在高达约1tev的能量尺度上的相互作用。为了充分利用这种加速器的物理机会，必须设计出一种粒度、鲁棒性和精度前所未有的粒子物理探测器，并证明其可行性。ILD以粒子流为基础，这是一种旨在重建单个粒子的范例，使用以时间投影室为中心的高度健壮的跟踪系统，辅以硅跟踪，以及适合分离单个能量沉积物的高粒度“类似相机”的电磁和强子量热仪。粒子流量热计提供了一种令人兴奋的新方法，以实现新物理学所需的更好的能量分辨率。如果证明有效，它们将在高能和核物理实验中的许多未来应用中发挥作用。该建议将支持使用测试束数据的粒子流算法的开发和验证。探测器项目解决了与推进ILD探测器设计相关的互补方面，重点是跟踪，量热以及光束仪器。该方案将支持低质量TPC端板和光度监测系统的开发。该提案将产生更广泛的影响，因为许多研发项目利用了大量高度融入计划研究的本科生。大学团体在鼓励代表性不足的群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得到应用，并将培养一批在实验艺术和探测器技术方面受过良好训练的科学家骨干。

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.
