Low two-level-system noise in hydrogenated amorphous silicon

Fabien Defrance, Andrew D. Beyer, Jordan Wheeler +2

At sub-Kelvin temperatures, two-level systems (TLS) present in amorphous dielectrics source a permittivity noise, degrading the performance of a wide range of devices using superco…

NEW-MUSIC: The Next-generation Extended-Wavelength Multiband Sub/millimeter Inductance Camera

Sunil R. Golwala, Andrew D. Beyer, Daniel Cunnane +9

The Next-generation Extended Wavelength-MUltiband Sub/millimeter Inductance Camera (NEW-MUSIC) on the Leighton Chajnantor Telescope (LCT) will be a first-of-its-kind, six-band, tra…

Characterization of the low electric field and zero-temperature two-level-system loss in hydrogenated amorphous silicon

Fabien Defrance, Andrew D. Beyer, Shibo Shu +2

Two-level systems (TLS) are an important, if not dominant, source of loss and noise for superconducting resonators such as those used in kinetic inductance detectors and some quant…

Hierarchical phased-array antennas coupled to Al KIDs: a scalable architecture for multi-band mm/submm focal planes

Jean-Marc Martin, Junhan Kim, Fabien Defrance +5

We present the optical characterization of two-scale hierarchical phased-array antenna kinetic inductance detectors (KIDs) for millimeter/submillimeter wavelengths. Our KIDs have a…
