Urgent repair of our existing Physical Property Management System (PPMS) is crucial to advance the research programs of five groups in Chemistry and Physics at Brock University. The core of the PPMS comprises a cryogenic chamber, enabling samples to be studied at temperatures from 400 to 1.8 K and a magnet generating fields up to 9 Tesla. Its modular nature supports a diverse set of `options' for the measurement of a range of material properties. It was first installed in 2012 and apart from a failed Alternating Current (AC) module, all its other components are in excellent working order. Reserchers at Brock desperately need access to the AC option to study the magnetic properties of a broad range of materials. Over the past decade, this instrument has supported the practical training of > 60 highly qualified personnel (HQP) that includes course and research-based graduate students, postdoctoral researchers (PDFs) and visiting scholars. Unfortunately, the original ACMS(I) option contains components (coils and quartz tubes) that have become irreparably damaged over time. Due to its age, repair is not possible as parts are no longer available, and the unit is no longer supported by the manufacturer. To replace this component, we are requesting an upgrade to the newest ACMS(II) option available from the manufacturer, and to the modular control system to ensure that the electronics are fully compatible with our existing instrumentation. These upgrades will result in improved performance and considerably extend the lifetime of the PPMS by 15+ years. The consortium of (co)applicants and users submitting this application includes chemists studying molecule-based magnetic materials and physicists studying the optical and magnetic properties of condensed soft matter. The team of researchers and HQP are representative of the diversity of gender, culture, ethnicity, and racial background at Brock University. Restored access to the proposed infrastructure will enable us to continue to provide excellent training to our HQP who include members of under-represented groups. This shared infrastructure will further the diversity of research and working relationships at Brock, serve as a hub to facilitate new collaborative ideas, and provide networking opportunities for HQP outside of their home departments. The newly upgraded PPMS will facilitate 24/7 access of the equipment to internal and external users that will underpin new collaborations and research partnerships and help offset costs. The upgraded ACMS(II) option will enable Brock researchers to study slow relaxation phenomena of new molecules and materials as "stepping-stones" for the development of emerging technologies such as quantum computers, that over the next decade promise to radically transform banking and finance services, space and defense, energy and power, healthcare and pharmaceutical research and development.

紧急修复我们现有的物理属性管理系统（PPMS）对于推进布鲁克大学化学和物理五个小组的研究项目至关重要。PPMS的核心包括一个低温室，使样品能够在400至1.8 K的温度下进行研究，并产生高达9特斯拉的磁场。它的模块化特性为测量一系列材料属性提供了多种“选项”。它于2012年首次安装，除了一个故障的交流（AC）模块外，所有其他组件都处于良好的工作状态。布鲁克大学的研究人员迫切需要交流电来研究各种材料的磁性。在过去的十年中，该仪器支持了60名高素质人才（HQP）的实践培训，其中包括以课程和研究为基础的研究生，博士后研究人员（pdf）和访问学者。不幸的是，原始的ACMS(I)选项包含的组件（线圈和石英管）随着时间的推移已经不可挽回地损坏。由于它的年龄，维修是不可能的，因为零件不再可用，该单位不再由制造商支持。为了取代该组件，我们要求升级到制造商提供的最新ACMS（II）选项，并升级到模块化控制系统，以确保电子设备与我们现有的仪器完全兼容。这些升级将提高性能，并将PPMS的使用寿命大大延长15年以上。提交此申请的（co）申请人和用户联盟包括研究分子基磁性材料的化学家和研究凝聚态软物质的光学和磁性质的物理学家。研究团队和HQP代表了布鲁克大学性别、文化、民族和种族背景的多样性。恢复使用拟议的基础设施将使我们能够继续向我们的HQP提供优秀的培训，其中包括代表性不足的群体的成员。这种共享的基础设施将进一步促进Brock研究和工作关系的多样性，作为促进新合作想法的中心，并为HQP在其国内部门之外提供网络机会。新升级的PPMS将为内部和外部用户提供24/7的设备访问，这将支持新的合作和研究伙伴关系，并有助于抵消成本。升级后的ACMS（II）选项将使Brock的研究人员能够研究新分子和材料的慢弛豫现象，作为量子计算机等新兴技术发展的“垫脚石”，这些技术有望在未来十年从根本上改变银行和金融服务、空间和国防、能源和电力、医疗保健和制药研发。
