Cryogen-Free Dilution Refrigerator System for Studies of Superconductor-Quantum Hall Hybrid Samples

Abstract

Major Goals: The goal of this project was to purchase and install a cryogen-free dilution refrigerator with a base temperature of 10 mK and magnetic fields up to 12 Tesla. The refrigerator is to be dedicated to measuring superconductor - quantum Hall hybrid samples. Accomplishments: The PI's group has purchased and installed Triton 500 dilution refrigerator with a 12 Tesla magnet. The instrument was installed and fully tested in 2019, and in 2020 the PI's group upgraded the cryogenic wires and filters to greatly improve the electrical measurements that could be performed with this instrument. Training Opportunities: The cryogen-free dilution refrigerator allows graduate students to spend more time working on the challenging low-noise electronic measurements at cryogenic temperatures, contributing to their professional growth.
