The primary activity of the Northern Illinois University (NIU) experimentalelementary particle physics research program is the exploration of thesub-microscopic world with the DZERO detector. The detector, constructed andoperated by a 500-member international collaboration and located at theFermilab National Accelerator Laboratory, is a large, general-purpose devicedesigned to observe and study proton-antiproton collisions produced at theTevatron. The Tevatron is the world's highest energy accelerator. Presently the group is involved in preparation for the second 5-year data collection period of DZERO, and has responsibility for the construction and operation of a muon particle detector, muon triggering, and muon reconstruction software. The group also has overall responsibility for the full DZERO triggering and data acquisition systems. The NIU group will focus on continued searches for new forms of matter, such as the Higgs particle, which is thought to give mass to all other particles, and supersymmetry, which postulates heavy partners to all already discovered particles. Over the past decades advances in particle physics have resulted in theconstruction and confirmation of the Standard Model which describes in greatdetail and accuracy the interactions of the fundamental particles. Thetheory is incomplete and there are hints that new forces and particles arerequired to fully describe the microscopic world. In particular the numbersof particles and the origins of their mass are great mysteries. The secondrun of the DZERO detector will offer an opportunity to discover themechanism that lends mass to particles and an over-arching theory thatunifies the description of the microscopic world. This run will exploit theimprovements to Fermilab's accelerator complex which have recently beencompleted, allowing significantly more sensitive searches to be made. At amore immediate level, over the past decade the ongoing NIU particle physicsprogram has offered research experiences to more than 100 undergraduates andMaster's students. These graduates have accepted employment withtechnological firms, the financial industry, governmental agencies, andacademic institutions. A great number of the students have become highschool physics instructors. The NSF sponsored program will continue tooffer opportunities and support to these students as well as PhD studentsadmitted into the new NIU physics doctoral program.

北伊利诺伊大学（NIU）实验性元素物理学研究计划的主要活动是对Thesub-Microscopic World的探索，并使用DZERO探测器进行了探索。该探测器由由500名成员组成的国际合作构建，位于Thefermilab国家加速器实验室，是一个大型的通用depsedessignedsignedsignedsignedsignessign，可观察和研究在thetevatron上产生的质子 - 抗抗球菌碰撞。 Tevatron是世界上最高的能量加速器。目前，该小组参与了DZERO的第二个5年数据收集期的准备，并负责MUON粒子探测器，MUON触发和MUON重建软件的构建和操作。该小组还对完整的Dzero触发和数据采集系统负有总体责任。 NIU组将继续搜索新形式的物质，例如希格斯粒子，该粒子被认为会给所有其他粒子和超对称性提供质量，这将较重的伴侣推为已经发现的颗粒。在过去的几十年中，粒子物理学的进步导致了标准模型的结构和确认，该模型在巨大的尾巴和准确性中描述了基本颗粒的相互作用。 Thetheory是不完整的，并且有一些暗示新力量和颗粒以充分描述微观世界。 尤其是粒子的数量及其质量的起源是伟大的奥秘。 DZERO检测器的第二次将提供一个机会，以发现将质量借给粒子和架构的理论赋予微观世界的描述的主体机制。 这种运行将利用最近已完成的Fermilab加速器复合物的进展，从而可以进行更敏感的搜索。 在过去的十年中，正在进行的NIU粒子物理计划为100多名本科生和硕士的学生提供了研究经验。这些毕业生已经接受了技术公司，金融行业，政府机构，核心学院的就业。 许多学生已成为高中物理教师。 NSF赞助计划将继续为这些学生以及新的NIU物理博士学位课程提供给这些学生的机会和支持。
