The acquisition of a cryogen-free and integrated Physical Property Measurement System (PPMS) at the University of Utah is a significant advancement that bolsters the research activities in quantum science, bioengineering, and manufacturing at various universities and companies across Utah and the surrounding States. The state-of-the-art PPMS tool enables researchers to investigate the behavior of materials at low temperatures without the need for helium to operate and under various external conditions such as magnetic fields, pressure, and sample rotating angles. The utilization of multifunctional characterization tools like the PPMS is crucial for pushing the frontiers of material understanding and designing new materials with controllable properties. The PPMS's ability to provide conclusive insights into electrical, optical, thermal, and magnetic properties with high spatial resolution greatly benefits the research community within the Intermountain West region. The instrument meets the critical needs of research, education, and training by a diverse and large group of faculty within the Colleges of Science, Mines & Earth Sciences, Engineering, and the School of Medicine. The inclusion of several magneto-optic interfaces adds even more value to the PPMS acquisition. The ability to investigate the ferromagnetic responses of quantum materials using a cryo-ferromagnetic resonance spectroscopy probe is a unique capability that currently does not exist in any facility in the State of Utah and its surrounding regions. This specific feature makes the PPMS a unique capability that fosters collaboration with major semiconducting companies in the area. As such, the PPMS serves as a major open-access user facility where students and staff are constantly trained in the areas of microelectronics, semiconductors, and device engineering. More importantly, students and postdocs across many institutions (R1, R2, and primarily undergraduate institutions) strongly overlap with scientists at regional companies and government laboratories, which allow them to seek internships and job opportunities in the region, furthering scientific advancements and innovation in material science.Pushing the frontiers of understanding the physical behavior of materials and designing new materials with controllable properties demands the utilization of multifunctional characterization tools that can provide conclusive electrical, optical, thermal, and magnetic property insights with sufficient spatial resolution. The cryogen-free and integrated PPMS provides a powerful capability to characterize the physical properties of materials at very low temperatures (100 mK-400 K) and as a function of magnetic fields, pressure, and sample rotating angles. The location of the PPMS within the Materials Core Laboratory at the University of Utah boosts the research of regional companies, promote collaborative research, enhances existing lab outreach activities to underrepresented students in STEM fields, and expands educational programs. The PPMS includes several magneto-optic interfaces to investigate the ferromagnetic responses of quantum materials using a cryo-ferromagnetic resonance spectroscopy probe, a unique capability not present in any facility in the State of Utah and its surroundings. There are currently 11 regional companies that make use of PPMS and help to spur the State’s burgeoning technology industry. The University of Utah offers certificates in microscopy, diffraction, and nanotechnology which are enriched by the addition of the PPMS. Finally, the PPMS data acquired by underrepresented undergrads are presented to the public in a Spanish seminar series where various Spanish-speaking professors and students doing cutting-edge science deliver seminars to inform Hispanic families about the importance of a particular scientific topic. Finally, the cryogen-free PPMS allows users to decrease helium consumption in research activities as well as train and expand the microelectronic workforce in coordination with industry and national laboratories within the State and its surroundings.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

犹他大学购买无冷冻剂的集成物理特性测量系统 (PPMS) 是一项重大进步，它支持了犹他州及周边各州各大学和公司在量子科学、生物工程和制造方面的研究活动。最先进的 PPMS 工具使研究人员能够研究材料在低温下的行为，而无需氦气操作以及在磁场、压力和样品旋转角度等各种外部条件下的多功能表征的利用。像这样的工具PPMS 对于推动材料理解的前沿和设计具有可控特性的新材料至关重要。 PPMS 能够以高空间分辨率提供关于电、光、热和磁特性的结论性见解，这极大地有利于山间西部地区的研究界。该仪器满足了科学学院、矿业与地球科学学院、工程学院和医学院的众多教员的研究、教育和培训的关键需求，还增加了多个磁光接口。使用低温铁磁共振光谱探头研究量子材料的铁磁响应的能力对 PPMS 的收购具有更大的价值，这是一项独特的能力，目前犹他州及其周边地区的任何设施都不具备这种能力。该功能使 PPMS 成为一种独特的功能，可以促进与该领域主要半导体公司的合作。因此，PPMS 是一个主要的开放访问用户设施，学生和员工可以在以下领域不断接受培训。更重要的是，许多机构（R1、R2，主要是本科机构）的学生和博士后与地区公司和政府实验室的科学家有重叠，这使他们能够在该地区寻求实习和工作机会。 ，进一步推动材料科学的科学进步和创新。推动理解材料物理行为的前沿并设计具有可控特性的新材料需要利用多功能表征工具，这些工具可以提供结论性的电、光、热和磁性能具有足够空间分辨率的属性洞察力，无冷冻剂和集成 PPMS 提供了强大的功能来表征材料在极低温度 (100 mK-400 K) 下的物理属性，并作为磁场、压力和样品旋转角度的函数。 PPMS 位于犹他大学材料核心实验室内，促进了区域公司的研究，促进了合作研究，加强了针对 STEM 领域代表性不足的学生的现有实验室外展活动，并扩展了教育项目。多个磁光接口，使用冷冻铁磁共振光谱探头研究量子材料的铁磁响应，这是犹他州及其周边地区任何设施都不具备的独特功能。目前有 11 家地区公司使用 PPMS。犹他大学提供显微镜、衍射和纳米技术方面的证书，这些证书因 PPMS 的加入而更加丰富。最后，代表性不足的本科生获得的 PPMS 数据在西班牙语研讨会系列中向公众展示，其中讲西班牙语的教授和从事尖端科学的学生举办研讨会，向西班牙裔家庭介绍特定科学主题的重要性。无冷冻剂 PPMS 允许用户减少研究活动中的氦气消耗，并与该州及其周边地区的行业和国家实验室协调培训和扩大微电子劳动力。该奖项反映了 NSF 的法定使命，并已通过使用基金会的智力优点和更广泛的影响审查标准进行评估，认为值得支持。
