Cryogenic Thermometer Based On A Two-Level System (TLS)

NIST Inventors

Michael Vissers , Jordan Wheeler and Maxime Malnou

We have invented a new type of cryogenic thermometer for use at temperature below 1 Kelvin. The device consists of a superconducting resonator with dielectric two-level systems (TLS) material deposited or naturally formed on the surface. The temperature is read out by measuring the resonance
