This proposal requests support for the University of Notre Dame (UND) high energy physics group, whose activities include the D0 experiment at the Tevatron, the CMS experiment at the CERN/LHC, the Linear Collider Project, and Education and Outreach through QuarkNet and RET. Their physics objectives are to study top and beauty physics, the electroweak bosons, W and Z, and QCD processes and to search for evidence of electroweak symmetry breaking, supersymmetry, extra (hidden) spatial dimensions and other new phenomena. UND plays a central role in the Run II upgrade of the D0 experiment. Currently, members of the group are managing the operation and commissioning of the Central Fiber Tracker (CFT), directing the offline track reconstruction, and taking the lead in analysis groups such as Searches for New Phenomena and Higgs Searches. UND has been instrumental in developing and designing the Trigger Upgrade to exploit the higher luminosities expected in Run IIb. The CMS experiment is nearing the end of its construction phase and is beginning the operation and commissioning phase at the Surface Hall SX5. UND's contribution has been the design and production of readout boxes (RBX) and optical decoder units (ODU), which are electro-optical interfaces for the barrel, outer barrel and endcap hadron calorimeter (HCAL) subsystems. UND expects to participate in the continued beam testing of HCAL elements and the testing of the readout chain of detector subsystems. Additionally, they intend to work on R&D for upgrades of CMS calorimetry. The Linear Collider Projects are in the beginning phase and UND is involved in R&D in Calorimetry, Muon and Accelerator Subsystems. Their educational objectives are not only to train postdoctoral researchers, graduate and undergraduate students but, in addition, to make significant efforts to engage non-traditional participants, high school teachers and high school students, in immersive research experiences in particle physics at the scientific frontier. QuarkNet is now in its fifth year and UND is one of the four institutions leading this national project that currently consists of 50 Centers in 30 States and Puerto Rico.

该提案要求支持圣母大学（UND）高能物理组，其活动包括Tevatron的D0实验，CERN/LHC的CMS实验，线性对撞机项目以及通过QuarkNet和RET进行的教育和推广。他们的物理学目标是研究顶和美物理，电弱玻色子，W和Z，QCD过程，并寻找电弱对称性破缺，超对称性，额外（隐藏）空间维度和其他新现象的证据。 UND在D0实验的运行II升级中起着核心作用。目前，该小组的成员正在管理中央纤维跟踪器（CFT）的运行和调试，指导离线轨道重建，并在新现象和希格斯粒子等分析小组中发挥主导作用。UND在开发和设计触发升级方面发挥了重要作用，以利用Run IIb中预期的更高亮度。CMS实验已接近其建设阶段的尾声，并开始在Surface Hall SX5的运行和调试阶段。UND的贡献是设计和生产读出盒（RBX）和光学解码器单元（ODU），这是桶，外桶和端盖强子量能器（HCAL）子系统的电光接口。 UND希望参与HCAL元件的持续束流测试和探测器子系统读出链的测试。此外，他们还打算进行CMS量热法升级的研发工作。&直线对撞机项目正处于起步阶段，UND参与了量热、μ子和加速器子系统的研发。&他们的教育目标不仅是培养博士后研究人员，研究生和本科生，而且还努力让非传统参与者，高中教师和高中学生参与科学前沿粒子物理学的沉浸式研究体验。 QuarkNet现已进入第五个年头，UND是领导这一国家项目的四个机构之一，该项目目前由30个州和波多黎各的50个中心组成。
