Cryogen-free dilution refrigerator with vector magnet
Abstract
A closed-cycle, versatile, cryogen-free dilution refrigerator system with integrated superconducting vector magnet field capability is proposed. The instrument will be operated at the University of California, Santa Barbara (UCSB). The proposed instrument addresses critical needs in the development of new materials and their characterization in a wide range of interdisciplinary, Department of Defense-funded research projects at UCSB, which require electrical transport and thermodynamic measurements at low temperatures and under different configurations of applied magnetic fields. These projects focus on the discovery, manipulation, and characterization of novel topological materials, including those harboring strong electron-electron interactions, new quantum phenomena, the development of new measurement techniques for topological matter, the characterization of unconventional superconductors and the measurement of devices relevant for quantum information sciences. The proposed system takes advantage of recent developments in dilution refrigerator technologies that greatly facilitate operation, allow for lower operational costs, and for a high throughput of samples. The proposed instrument will greatly expand the training opportunities for graduate and undergraduate researchers, who will be the primary hands-on users.
