***9722562ReucroftThe Compact Muon Solenoid (CMS) is one of two US supported experiments to be built at the CERN Large Hadron Collider (LHC). The primary physics goal of CMS is to discover the origin of electroweak symmetry breaking. To that end, the basic philosophy of CMS is to enclose the tracking and calorimetryinside a strong Solenoidal magnet. This design allows for a Compact design allowing optimal Muon detection without compromise to the electromagnetic calorimetry because of inert material. In general CMS is optimized for detection of electrons, photons, muons, neutrinos and jets. The Standard Model predicts the existence of the Higgs Particle, the missing component of the model. Reconstruction of the Higgs decay modes predicted by theStandard Model requires excellent lepton detection. At the highluminosities to be used at the LHC, the lepton of choice is the muon due to its relatively clean signature. There are about 1500 physicists in the CMS Collaboration who plan to build the detector. The detector is to be constructed from 1998 until data taking in mid 2005. The composition of CMS is roughly 50% physicists from member states, 25% from Russia and other non member states, and 25% US groups. During 1994 a US CMS Collaboration of about 320 physicists and engineers from 40 institutions (4 national labs) was formed. The collective goal of this group is to pursue high energy physics at the highest energy frontier which will be available at LHC.Their experience on previous hadron collider experiments at Fermilab and CERN and on the R&D associated with the SSC makes it possible for US physicists to have a major impact on the design of CMS. They have been assigned distinct and coherent managerial and construction responsibilities. including the management for the hadron calorimetry (HCAL), the endcap muon system (EMU), the trigger system (TRIG), construction responsibilities in electron calorimetry (ECAL), tracking, data acquisition (DAQ) and computing and software. The present design of the HCAL barrel and the EMU are the result of US CMS redesigning those parts of the detector. CMS has appointed, in addition to detector coordinators, an education coordinator who, with a CMS education task group, intends to develop a sustained program integrating research and education.***.

*** 9722562 REAUCROFTTHE THE COMPACT MUON电磁阀（CMS）是在CERN大型强子撞机（LHC）上建造的两个美国支持的实验之一。 CMS的主要物理目标是发现Electroweak对称性破坏的起源。为此，CMS的基本哲学是将跟踪和量热法包裹有强的螺线管磁体。这种设计允许进行紧凑的设计，可以通过惰性材料而不会损害电磁量热法而在不妥协的情况下进行最佳的锥形检测。总体而言，CMS被优化用于检测电子，光子，兆子，中微子和喷气机。 标准模型预测了希格斯粒子的存在，这是模型的缺失成分。 thestandard模型预测的希格斯衰减模式的重建需要出色的Lepton检测。在LHC在LHC上使用的高光剂，首选的Lepton是Muon，因为它相对干净。 CMS合作中大约有1500名物理学家计划建造检测器。该探测器应从1998年到2005年中期的数据构建。CMS的组成约为来自成员国的50％物理学家，俄罗斯和其他非成员国的25％，美国25％。 在1994年期间，成立了来自40个机构（4个国家实验室）的约320名物理学家和工程师的美国CMS合作。该小组的集体目标是在最高能源边界进行高能物理，这将在LHC上获得。他们在Fermilab和Cern的先前强子撞机实验以及与SSC相关的R＆D上的经验使美国物理学家对CMS设计产生重大影响。他们被分配了独特的管理和建筑责任。包括强子量热法（HCAL），端盖MUON系统（EMU），触发系统（TRIG），电子量热法（ECAL）的施工责任，跟踪，数据采集（DAQ）以及计算和软件的管理。 HCAL枪管和EMU的当前设计是美国CMS重新设计检测器的那些部分的结果。 CMS还任命了一个教育协调员，除了检测器协调员外，他与CMS教育任务小组一起打算制定一项持续的计划，将研究与教育整合在一起。***。
