CCAT: Mod-Cam Cryogenic Performance and Its Impact on 280-GHz KID Array Noise

Lawrence T. Lin, Eve M. Vavagiakis, Jason E. Austermann, James Burgoyne et autres

The CCAT Observatory's Fred Young Submillimeter Telescope (FYST) is designed to observe submillimeter astronomical signals with high precision, using receivers fielding state-of-the-art kinetic inductance detector (KID) arrays. Mod-Cam, a first-light instrument for FYST, serves as a testbed for instrument module characterization, including …

Kinetic Inductance Traveling Wave Parametric Amplifiers Near the Quantum Limit: Methodology and Characterization

L. Howe, A. Giachero, Michael Vissers, Pietro Elia Campana et autres

We present a detailed simulation and design framework for realizing traveling wave parametric amplifiers (TWPAs) using the nonlinear kinetic inductance of disordered superconductors -- in our case niobium-titanium-nitride (NbTiN). These kinetic inductance TWPAs (KITs) operate via three-wave mixing (3WM) to achieve high …

Low two-level-system noise in hydrogenated amorphous silicon

Fabien Defrance, Andrew D. Beyer, Jordan Wheeler, Jack Sayers et autres

At sub-Kelvin temperatures, two-level systems (TLSs) present in amorphous dielectrics source a permittivity noise, degrading the performance of a wide range of devices using superconductive resonators such as qubits or kinetic inductance detectors. We report here on measurements of TLS noise in …
