This CAREER proposal is for the development of novel solid state detectors for experimental particle physics research, and for creating a science outreach program designed for girls in impoverished rural settings. The PI, Julia Thom of the Department of Physics at Cornell University, will lead a program to develop silicon pixel detectors for the Compact Muon Spectrometer at the upgraded Large Hadron Collider (Super-LHC) at CERN. The research goal to understand the origin of electroweak symmetry breaking relies on the precise measurement of charged particle trajectories provided by silicon pixel detectors. In the Standard Model of elementary particle physics, electroweak symmetry breaking is associated with the existence of a Higgs particle which has yet to be discovered. While the discovery of the Higgs Boson is most likely to occur at the standard LHC, the increased luminosity at the Super-LHC will provide the statistical power to study its properties in detail. The discovery of the Higgs particle and the measurement of its quantum numbers are of utmost importance in particle physics today. The proposed program includes design, simulation and testing of cutting-edge pixel sensor technology that can withstand the extremely high radiation doses and tracking densities at the Super-LHC. This work will be carried out in collaboration with researchers at the Fermi National Accelerator Laboratory and partners in industry. Based at Cornell University in upstate New York, the PI has learned that there are no regular science education programs that target schools in surrounding poor rural communities. In particular, the number of girls in this region pursuing higher education in science or engineering is alarmingly low. The proposal includes initiating a program that provides mentoring and science summer camps for girls, teacher workshops, and regular visits to six schools that have been classified as high-need and that show particular interest in this program. The program will be implemented in collaboration with a professional educator, whose research interest in science education in rural poverty settings matches the goals of the PI.Intellectual Merit:The development of a new silicon pixel detector is essential to take advantage of the luminosity upgrade of the LHC for detailed studies of many of the new and possibly revolutionizing phenomena that are expected at the TeV energy scale. Since no known technology can withstand the enormous particle rates expected at the Super-LHC, the development of innovative silicon pixel detector technology built on the recent progress of the silicon processing industry would be a breakthrough in the field of particle detection. If successful, this development would have many important applications in x-ray imaging for biology and astrophysics.Broader Impact: The research project requires an extensive collaboration between the FermiNational Accelerator Laboratory, the School of Electrical and Computer Engineering at Cornell, and partners in industry. The project provides an opportunity to provide graduate and undergraduate students with the experience of interdisciplinary research at the cutting-edge of pixel detector technology. The science education program would encourage girls in underserved rural areas to pursue careers in science and engineering, serve as a tool for the professional development of teachers, and bring the excitement of science to the broader community.

该职业建议是为了开发用于实验粒子物理研究的新型固态探测器，以及为贫困农村环境中的女孩设计的科学外展计划。康奈尔大学物理系的PI，朱莉娅·托姆（Julia Thom）将领导一项计划，以开发升级的大型强子对撞机（Super-LHC）的紧凑型MUON光谱仪的硅像素探测器。理解电子对称性破坏的起源的研究目标取决于硅像素探测器提供的带电颗粒轨迹的精确测量。在基本粒子物理学的标准模型中，electroweak对称性断裂与尚未发现的希格斯粒子的存在有关。虽然Higgs玻色子的发现最有可能在标准LHC上发生，但Super-LHC处的发光度增加将提供详细研究其特性的统计能力。希格斯粒子的发现及其量子数的测量在当今粒子物理学中至关重要。拟议的程序包括设计，模拟和测试尖端像素传感器技术，这些技术可以承受超级LHC处的极高辐射剂量和跟踪密度。这项工作将与费米国家加速器实验室和行业合作伙伴的研究人员合作进行。 PI位于纽约州北部的康奈尔大学（Cornell University），他了解到没有定期的科学教育计划针对贫困农村社区的学校。特别是，该地区从事科学或工程高等教育的女孩数量令人震惊。该提案包括启动一项计划，为女孩，教师讲习班提供指导和科学夏令营，并定期访问六所被归类为高需求的学校，并对该计划特别感兴趣。该计划将与专业教育者合作实施，该计划对农村贫困环境的科学教育的研究兴趣与PI.Intlectual功绩的目标相匹配：开发新的硅像素探测器对于利用LHC的亮度升级的LHC的亮度升级至关重要。由于没有已知的技术可以承受Super-LHC上预期的巨大粒子速率，因此建立在硅处理行业最近进步的创新硅像素检测器技术的发展将是粒子检测领域的突破。如果成功的话，这一发展将在生物学和天体物理学的X射线成像中有许多重要的应用。Boader的影响：研究项目需要Ferminational Accelerator实验室，Cornell的电气和计算机工程学院与工业合作伙伴之间进行广泛的合作。该项目提供了一个机会，可以为研究生和本科生提供在像素探测器技术的前沿进行跨学科研究的经验。科学教育计划将鼓励服务不足的农村地区的女孩从事科学和工程学的职业，作为教师专业发展的工具，并将科学兴奋带给更广泛的社区。
