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.

我们现有的物理财产管理系统（PPM）的紧急修复对于推进布罗克大学化学和物理学五组的研究计划至关重要。 PPM的核心包括一个低温室，可以在400至1.8 K的温度下研究样品，并产生高达9特斯拉的磁铁。它的模块化性质为测量一系列材料属性提供了一组“选项”集。它是在2012年首次安装的，除了失败的交替电流（AC）模块外，其所有其他组件都处于良好的工作状态。 Brock的Reserchers迫切需要使用AC选项来研究各种材料的磁性。在过去的十年中，该乐器支持了60名高素质的人员（HQP）的实践培训，其中包括课程和研究的研究生，博士后研究人员（PDFS）和访问学者。 不幸的是，原始的ACM（i）选项包含随着时间的推移而损坏的组件（线圈和石英管）。由于其年龄，由于零件不再可用，因此无法维修，并且该设备不再得到制造商的支持。为了替换此组件，我们要求升级到制造商可提供的最新ACM（II）选项，并要求对模块化控制系统进行升级，以确保电子设备与我们现有的仪器完全兼容。这些升级将导致性能提高，并将PPM的寿命大大延长15年以上。 （CO）申请人和用户提交此应用的联盟包括研究基于分子的磁性材料的化学家以及研究凝结软物质的光学和磁性特性的物理学家。研究人员和HQP团队代表了布罗克大学的性别，文化，种族和种族背景的多样性。恢复对拟议的基础设施的访问将使我们能够继续为包括代表性不足群体的成员的HQP提供出色的培训。这种共同的基础架构将进一步促进布罗克的研究和工作关系的多样性，作为促进新协作思想的枢纽，并为HQP在其内部部门以外的HQP提供网络机会。新升级的PPM将有助于将设备24/7通向内部和外部用户，这将支持新的合作和研究合作伙伴关系，并有助于抵消成本。升级的ACM（II）选项将使Brock的研究人员能够研究新分子和材料的缓慢松弛现象，作为“垫脚石”，用于开发诸如量子计算机之类的新兴技术，这些技术在接下来的十年中有望从根本上转变，并且能够从根本上改变银行和财务服务，能源以及能源，能源，医疗保健，医疗保健和制药研究和开发。
