This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The award will fund Northern Illinois University (NIU) group in their research activities in the D0 experiment at FNAL, the ATLAS experiment at CERN, detector development (CALICE), as well as sustaining an extensive outreach program. The research program in D0 involves the search for associated production of Standard Model Higgs with the Z, top decays, charged Higgs and lepto-quark searches. As part of the search the group will continue to develop the muon and tau identification which are crucial for the selection of the channels of interest and for the rejection of background events. This program will continue the Tevatron is closed and the data analysis has been completed. The ATLAS experiment research program at CERN of this group has started and this proposal will is fund their investigation in to the properties of top production and decays, inclusive photon production at the LHC. These channels will also be used to improve the understanding of the detector performance. Once the detector performance is understood and sufficient integrated luminosity has been collected the research program will aims to search for neutral and changed Higgs. Looking into the more distant future the group is working on developing calorimetry for the International Linear collider. The effort concentrated on the tail-catcher and muon tracker behind the calorimeter. The detector consists of small (high granularity) scintillator element readouts by small solid state photodetectors (Si-PMTs). The push towards higher granularity in ILC calorimetry is a consequence of the particle-flow algorithm attempt to identify the electromagnetic components of the shower at all its stages. The broader interest areas the NIU group will continue an active outreach program that includes: school visits, physics Olympics, summer camps, QuarkNet, Halloween Haunted Physics Lab, etc. The university has a STEM outreach coordinator and several REU students moved on to graduate programs in physics and other sciences. In addition the group is involved in new initiatives to train personnel for the proton therapy center.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该奖项将资助北方伊利诺伊大学（NIU）小组在FNAL的D 0实验，CERN的ATLAS实验，探测器开发（CALICE）以及维持广泛的推广计划中的研究活动。D 0的研究计划涉及寻找标准模型希格斯粒子与Z的关联产生，顶部衰变，带电希格斯粒子和lepto-quark搜索。作为搜索的一部分，该小组将继续开发μ子和τ子识别，这对于选择感兴趣的通道和拒绝背景事件至关重要。Tevatron关闭且数据分析已完成时，该程序将继续。该小组在CERN的ATLAS实验研究计划已经开始，该提案将资助他们对顶级生产和衰变的性质的研究，包括LHC的光子生产。这些通道也将用于提高对探测器性能的理解。一旦探测器的性能得到理解，并收集了足够的积分光度，研究计划将致力于寻找中性和变化的希格斯粒子。 展望更遥远的未来，该小组正在为国际直线对撞机开发量热法。工作集中在量热计后面的尾捕捉器和μ子跟踪器上。该探测器由小型固态光电探测器（Si-PMT）读出的小型（高粒度）闪烁体元件组成。推动更高的粒度在ILC量热法的粒子流算法的结果，试图确定电磁组件的簇射在其所有阶段。更广泛的兴趣领域NIU集团将继续积极的外展计划，包括：学校参观，物理奥林匹克，夏令营，QuarkNet，万圣节闹鬼物理实验室等大学有一个STEM外展协调员和几个REU学生继续在物理和其他科学研究生课程。此外，该集团还参与了新的举措，为质子治疗中心培训人员。
