The MoEDAL Experiment at the LHC

2010年3月，欧洲核子研究中心研究委员会一致批准了MoEDAL实验。MoEDAL合作项目由来自世界各地的18个研究所组成。加拿大四所MoEDAL学院分别是：阿尔伯塔大学、不列颠哥伦比亚大学、康考迪亚大学和约克大学。MoEDAL实验的主要动机是寻找磁单极子和双子的直接产生，以及其他以高电离、长寿命带电大质量粒子（SMPs）的形式出现的新物理学的象征，如：黑洞残余物、双荷希格斯粒子、睡眠子、r -强子、技术重子、q球、d粒子、奇克、奇异子等。重要的是，MoEDAL可能会在许多理论领域做出潜在的革命性的、改变范式的发现。例如，许多人认为磁单极子的发现将对科学产生革命性的影响，其影响要大于希格斯玻色子的发现。主要的MoEDAL探测器部署在LHCb交叉区域周围，是迄今为止部署在加速器上的最大的塑料核轨道探测器（NTD）堆栈和捕获探测器阵列（超过260平方米）。MoEDAL具有双重性。首先，作为“拍摄”新物理的巨型相机，NTD系统是相机的“胶片”；其次，作为新的大质量稳定粒子的物质陷阱分析仪。可能的辐射诱发背景将由一系列创新的TimePix硅像素成像芯片在线监测。MoEDAL不存在严重阻碍其他两个大型强子对撞机探测器ATLAS或CMS检测缓慢移动的高电离粒子的问题。因此，MoEDAL的物理范围补充了现有的通用大型强子对撞机实验，并建立在现有的加拿大参与大型强子对撞机的基础上。尽管MoEDAL NTD和TimePix测试阵列已经就位，但完整的MoEDAL探测器要到2013年长期停产后才能部署。MoEDAL实验将在2014/2015年LHC启动时正式开始采集14tev的数据，并将持续4-5年。

The CERN Research Board unanimously approved the MoEDAL experiment in March 2010. The MoEDAL collaboration is comprised of 18 institutes from around the world. The four Canadian MoEDAL Institutes are: the University of Alberta, UBC, Concordia University and York University. The prime motivation of the MoEDAL experiment is to search for the direct production of the magnetic monopoles and dyons as well as other avatars of new physics in the form of highly ionizing, long-lived electrically charged massive particles (SMPs), such as: black hole remnants, double charged Higgs particles, sleptons, R-hadrons, technibaryons, Q-balls, D-particles, Quirks, strangelets, etc. Importantly, MoEDAL could make potential revolutionary, paradigm shifting discoveries in a number of theoretical arenas. For example, many regard that the discovery of a Magnetic Monopole would have a revolutionary impact on science that is greater than that of the discovery of the Higgs boson. The main MoEDAL detector, deployed around the LHCb intersection region, is the largest array (over 260 sqm) of plastic Nuclear Track Detector (NTD) stacks and trapping detectors ever deployed at an accelerator. MoEDAL has a dual nature. First, as a giant camera for "photographing" new physics where the NTD systems are the camera's "film" and second as a matter trap analyzer for new massive stable particles. Possible radiation induced backgrounds will be monitored online by an array of innovative TimePix silicon pixel imaging chips. MoEDAL, does not suffer from the problems which would severely hamper detection of slow moving highly ionizing particles at the two other main LHC detectors, ATLAS or CMS. Thus, MoEDAL's physics reach complements that of the existing general purpose LHC experiments and builds on the existing Canadian involvement with the LHC. Although MoEDAL NTD and TimePix test arrays are in place - the full MoEDAL detector is not due to be deployed until the long shutdown in 2013. The MoEDAL experiment will officially start to take data at 14 TeV at the startup of the LHC in 2014/2015 and continue for 4-5 years.
