Superconducting Microwave Resonator Arrays for Submillimeter and Far-Infrared Imaging

Description

Superconducting microwave resonators have the potential to revolutionize submillimeter and far-infrared astronomy, and with it our understanding of the universe. The field of low-temperature detector technology has reached a point where extremely sensitive devices like transition-edge sensors are now capable of detecting radiation limited by the background noise of the universe. However, the size of these detector arrays are limited to only a few thousand pixels. In order to make substantial progress, next generation
ground-based telescopes such as CCAT or future space telescopes require focal planes with large-scale detector arrays. This work documents an effort to demonstrate the basic operation of 256 pixel arrays of lumped-element MKIDs made from superconducting TiN on silicon.
