Thermal Kinetic Inductance Detectors for Millimeter-Wave Astrophysics
Abstract
Thermal Kinetic Inductance Detectors (TKIDs) combine the excellent noise performance of traditional bolometers with a radio frequency (RF) multiplexing architecture that enables the large detector counts needed for the next generation of millimeter-wave instruments. Here we present dark prototype TKID pixels that demonstrate a noise equivalent power NEP = 2×10⁻¹⁷√W/Hz with a 1/f knee at 0.1 Hz, suitable for background-limited noise performance at 150 GHz from a ground-based site. We discuss the optimizations in the device design and fabrication techniques to realize optimal electrical performance and high quality factors at a bath temperature of 250 mK.
Additional Information
The research was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under contract with the NationalAeronautics and Space Administration. We thank the JPL Research and Technology Development (RTD) program for supporting funds, as well as the Dominic Orr Graduate Fellowship in Physics at Caltech for supporting Mr. Wandui's graduate research.Attached Files
