MRI-R2: Development of a Pixel Detector for the Upgraded CMS Experiment

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。随着大型强子对撞机（LHC）在今年秋天开始对撞束操作，粒子物理学正站在一个新发现时代的门槛上。凭借在实验室环境中创造的最高能量碰撞，CMS合作（全球约1600名物理学家）将研究我们这个时代一些最基本的问题，例如质量的起源，超对称的可能存在，以及额外空间维度的假设存在。紧凑介子螺线（CMS）是大型强子对撞机的两个通用探测器之一（另一个探测器被称为ATLAS，有类似数量的合作者），被设计用来发现这种能量尺度的新物理学。CMS的核心是硅像素探测器。目前的设备花了数年的时间来设计和建造，代表了这种类型探测器的最先进水平。然而，众所周知，由于辐射损伤，它最终会失效，必须设计和制造一种具有增强特性的新设备来取代它。该奖项资助了堪萨斯大学物理学教授Alice Bean教授和六所大学（堪萨斯大学、堪萨斯州立大学、伊利诺伊大学芝加哥分校、波多黎各-马亚格斯大学、莱斯大学和罗格斯大学）组成的联盟，以开发一种探测器，该探测器将作为设计用于CMS的第一阶段升级硅像素探测器的研究工具。更广泛的影响可以分为两类——与合作机构的研究和培训基础设施的发展有关的影响，以及与对整个高能物理领域的影响有关的影响。在粒子物理学中，设计和制造仪器的能力对任何大学团体在该领域的成功至关重要。该奖项为合作者提供了提高各自机构在国际上的声望和能力的手段。此外，发展活动将允许招收本科生，特别是妇女和少数民族，帮助建立这一仪器和参与物理研究，并应有助于吸引更多的学生进入物理和工程领域。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).Particle physics stands at the threshold of a new era of discovery as the Large Hadron Collider (LHC) begins colliding-beam operations this fall. With the highest-energy collisions ever created in a laboratory environment, the CMS collaboration (about 1600 physicists world-wide) will study some of the most fundamental questions of our time, such as the origin of mass, the possible existence of supersymmetry, and the hypothetical existence of extra spatial dimensions. The Compact Muon Solenoid (CMS), one of two general-purpose detectors at the LHC (the other detector is called ATLAS and has a similar number of collaborators), has been designed to discover the new physics of this energy scale. At the heart of CMS is the silicon pixel detector. The current device took years to design and build and represents the state-of-the-art for this type detector. However, it is well known that it will eventually fail due to radiation damage and a new device with enhanced characteristics must be designed and built to take its place. This award funds Professor Alice Bean, Professor of Physics at the University of Kansas, and a consortium of six universities (Kansas, Kansas State, Illinois at Chicago, Puerto Rico-Mayaguez, Rice, and Rutgers) to develop a detector that will serve as a research instrument for the design of the phase 1 upgraded silicon pixel detector for CMS.The broader impacts can be divided into two categories - those related to the development of the research and training infrastructure at collaborating institutions and those related to the impacts on the field of high energy physics as a whole. In particle physics the capability to design and build instrumentation is crucial to the success of any university group in this field. This award provides the means for the collaborators to enhance the prestige and capability of the respective institutions at an international level. In addition, the development activities will allow recruiting undergraduate students, especially women and minorities, to help build this instrument and participate in the physics studies and should help attract more students into physics and engineering.
