The National Institute of Standards and Technology (NIST) has established a Long Wavelength Sensors and Applications Group that specializes in developing advanced cryogenic instrumentation for measuring faint signals in the microwave to far-infrared wavelength range. This is achieved through the design and fabrication of custom devices based on superconductivity principles, operating at fundamental limits.
The group’s work has various applications, including precise measurements of the Cosmic Microwave Background and other astrophysical observables, as well as quantum sensing and microwave metrology. The technologies used in their research include transition edge sensor (TES) bolometers, microwave kinetic inductance detectors (MKIDs), SQUID multiplexers, parametric amplifiers, silicon feedhorns, and metamaterial lenslet arrays.
