Cryogen-free upgrade of a Physical Property Measurement System (PPMS) for support of materials research in the
Abstract
Project Abstract Over the last 10 years, the cost of liquid helium has risen dramatically and it has become increasingly difficult to obtain. This has led to a crisis that is negatively affecting research productivity in the USA. This proposal seeks funds to upgrade an existing Quantum Design Physical Property Measurement System (PPMS) to enable cryogen-free operation. The low operational cost and increased reliability afforded by this upgrade will significantly improve accessibility of the instrument in support of materials research for university personnel in the state of Montana. The research that will be affected includes many areas of DOD interest bridging chemistry, physics and materials science such as quantum information, thermal management (thermoelectrics and magnetocaloric materials), superconductivity, characterization of defects, specimen synthesis, singlecrystal growth, and the study of structure/property relations. Materials under investigation include thin-films, oxides, photonic materials and quasi-one-dimensional metals and magnets. The PPMS will be applied to measure electrical, magnetic and thermal properties of the materials over broad ranges of temperature and magnetic field. It is the only instrument in the state of Montana that is able to measure these properties. The requested upgrade will expand the number of users, reduce operational costs, and conserve helium. 1
