犹他州大学收购了一套无制冷剂的集成物理性能测量系统(PPMS)，这是一项重大进步，支持了犹他州及周边各州多所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，而不需要氦操作，以及在各种外部条件下，如磁场、压力和样品旋转角。像PPMS这样的多功能表征工具的使用对于推动材料理解的前沿和设计具有可控性能的新材料至关重要。PPMS能够以高空间分辨率对电学、光学、热学和磁学性质提供确凿的见解，这极大地造福了西部山间地区的研究界。该仪器满足了科学学院、矿业和地球科学学院、工程学院和医学院内各种不同的教职员工对研究、教育和培训的关键需求。几个磁光接口的加入为PPMS的收购增添了更多价值。使用低温铁磁共振光谱探测器研究量子材料的铁磁响应是一种独特的能力，目前犹他州及其周边地区的任何设施都不存在这种能力。这一特殊功能使PPMS成为一种独特的能力，可以促进与该地区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，学生和工作人员在这里不断接受微电子、半导体和设备工程领域的培训。更重要的是，许多机构(R1、R2，主要是本科生机构)的学生和博士后与地区公司和政府实验室的科学家有很强的重叠，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。推动了解材料物理行为和设计具有可控性能的新材料的前沿需要使用多功能表征工具，这些工具可以以足够的空间分辨率提供确凿的电、光、热和磁属性洞察。不含制冷剂的集成PPMS提供了强大的能力来表征材料在极低温度(100MK-400K)下的物理性质，并作为磁场、压力和样品旋转角的函数。PPMS在犹他大学材料核心实验室的位置促进了地区性公司的研究，促进了合作研究，加强了现有的实验室推广活动，面向STEM领域代表性不足的学生，并扩大了教育项目。PPMS包括几个磁光接口，可以使用低温铁磁共振光谱探测器来研究量子材料的铁磁响应，这是犹他州及其周围地区任何设施都不具备的独特能力。目前有11家地区性公司利用PPMS，帮助刺激该州蓬勃发展的技术产业。犹他大学提供显微镜、衍射和纳米技术方面的证书，而PPMS的加入丰富了这些证书。最后，由未被充分代表的本科生获得的PPMS数据将在西班牙语研讨会系列中向公众展示，在研讨会上，从事尖端科学的各种西班牙语教授和学生将举办研讨会，向西班牙裔家庭宣传特定科学主题的重要性。最后，无制冷剂PPMS允许用户减少研究活动中的氦消耗，并与该州及其周围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，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

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.
