项目摘要

The MoEDAL (Monopole and Exotics Detector at the LHC) is the 1st  "dedicated search experiment" to be deployed at  the LHC. It is designed to search for the highly ionizing  particle (HIP) avatars of new physics in a complementary way to the main LHC detectors, ATLAS and CMS. The MoEDAL experiment, led by the MoEDAL-Alberta group, is carried out by a international collaboration of 70 physicists. It is partially supported by an NSERC Discovery grant. MoEDAL started to take data in 2015 and has since then established the world's most stringent limits on:  multiply charged magnetic monopole production. It is also the first experiment to place limits on:  the direct production of spin1 monopoles; dyons, particles with electric and magnetic charge; and,  monopoles produced  in heavy-ion collisions via the Schwinger mechanism.  MoEDAL was also the first experiment to  place limits on monopole production via photon fusion at the LHC. MoEDAL papers reporting the world's best experimental limits  on massive electrically charged HIPs, are in the process of being submitted. MoEDAL will be reinstalled to take data at LHC's Run-3 starting in 2022 with the addition of a new sub-detector called MAPP (MoEDAL Apparatus for Penetrating Particles). MAPP's purpose is to expand MoEDAL's  physics reach to include the search for Feebly Interacting Particles, such as  mini-charged particles (mCP) with charge as low as 0.001e, where e is the electron charge. The funding for the construction of the MAPP-mcP detector was largely provided by a Category-2 RTI grant awarded in 2020.  MAPP-mCP consists of 4 collinear sections with cross-sectional area 1 sqm. Each section is comprised of 100 (10cm x 10cm x 75cm) scintillator bars readout by a fast, low noise PMT and specialized fast electronics. Thus, each through going particle will encounter 3m of scintillator, readout by 4 PMTs in coincidence. MAPP is protected from cosmic rays and SM particles from IP8, by: 100m rock overburden; at least 30 m of intervening rock; and, an active veto system. The MAPP-mCP detector will greatly extend the LHC's sensitivity to fractional charge which currently lies at only ~1/3e. This request has two parts. The 1st  part is for additional funding to finish the MAPP-mCP detector. This is required because our  Chinese PMT supplier (HZK) ceased trading in 2021  before all 400 PMTs were delivered, due to financial problems arising from the   Covid-19 pandemic. As a result we have to purchase the last 100 PMTs from Hamamatsu as a much higher price. We are asking for the difference is the cost between 100 HZK PMTs, already funded,  and 100 equivalent  Hamamatsu PMTs. The 2nd part of the request,  is for  an outrigger scintillator detector to improve the MAPP-mQP's acceptance for higher mass milli-charged particles. Here the funds are needed to provide additional scintillator material to add to a contribution of scintillator from the EXO-200 collaboration, in order to complete the detector.
MoEdal(LHC上的单极和Exotics检测器)是将在LHC部署的第一个“专用搜索实验”。它旨在搜索新物理学的高度电离粒子(髋关节)的化身,以通往主LHC探测器,地图集和CMS的完整方式。由Moedal-Alberta集团领导的Moedal实验是由70名物理学家的国际合作进行的。它得到了NSERC Discovery Grant的部分支持。 Moedal于2015年开始获取数据,此后建立了世界上最严格的限制:乘电动的磁性单极生产。这也是第一个对限制进行限制的实验:直接生产Spin1单极;底子,带电荷和磁性电荷的颗粒;并且,通过施温格机制在重离子碰撞中产生的单孔。 Moedal也是第一个通过LHC通过光子融合来对单极产生限制的实验。在提交的过程中,报告了世界上充电的臀部的世界上最佳实验限制。从2022年开始,将重新安装Moedal,以在LHC的Run-3上获取数据,并添加了一个名为MAPP的新子检测器(用于穿透颗粒的Moedal设备)。 MAPP的目的是扩大Moedal的物理范围,以包括搜索微弱的相互作用粒子,例如电荷低至0.001E的迷你电荷颗粒(MCP),其中E是电子电荷。 MAPP-MCP检测器建设的资金主要由2020年授予的2类RTI赠款提供。MAPP-MCP由4个共线截面组成,横截面区域为1平方米。每个部分由100(10厘米x 10厘米x 75厘米)的闪光灯杆组成,该闪光灯杆通过快速,低噪声PMT和专门的快速电子设备组成。那就是每个通过粒子遇到3M闪烁体的闪烁体,巧合的4个pmts读数。 MAPP免受IP8的宇宙射线和SM颗粒的保护,作者:100m岩石覆盖层;至少30m的介入岩石;并且,一个主动的否决系统。 MAPP-MCP检测器将极大地扩展LHC对当前所占电荷的敏感性。仅约1/3e。此请求有两个部分。第一部分是为了完成MAPP-MCP检测器的额外资金。这是必需的,因为我们的中国PMT供应商(HZK)于2021年停止了交易,在所有400 PMT交付之前,由于COVID-19-19的大流行引起的财务问题。结果,我们必须从Hamamatsu购买最后100个PMT,价格要高得多。我们要求的区别是已经资助的100个HZK PMT和100次同等的Hamamatsu PMT之间的成本。请求的第二部分是用于支撑闪烁剂探测器,以改善MAPP-MQP对更高质量毫米的颗粒的接受度。在这里,需要这些资金来提供其他闪烁材料,以增加exo-200的协作中闪烁体的贡献,以完成检测器。
