Ultra-Stable Kinetic Inductance Detectors for Astrophysical Observations
Project Description
This proposal seeks to implement a new KID design to reduce the low-frequency 1/f noise limiting the performance of this detector technology. This innovative design is based on work demonstrating near theoretically achievable current density in superconducting Nb nano-wires To reduce the 1/f noise, the inductive element in the resonator will be fabricated as a mesh. The proposed tasks involve fabrication of nano-mesh inductors out of Nb, TiN, and Al. The nano-meshes will be elements of superconducting resonators enabling characterization of the DC critical current and microwave response. The detailed microwave properties of the resonators, including quality factor, Q, and noise, will be characterized using existing instrumentation.
