Abstract

I will describe our development of a four kilopixel photometric imaging camera paired with a 1.5 meter crossed Dragone telescope. The focal plane is composed of aluminum kinetic inductance detectors (KIDs) fabricated on crystalline silicon tiles. The tiles contain 960 KIDs and are approximately 100 mm x 100 mm in size. KID pairs, each sensitive to an orthogonal linear polarization, are coupled to a waveguide/feedhorn machined from aluminum. A single block, with 480 waveguides/feedhorns arranged in a hexagonal close-pack configuration, is paired with each detector tile. Initial tests with prototype KID tiles show the expected noise and optical performance. Full-scale tiles have now been fabricated with >90% yield, and are currently being characterized. The imager is intended for terrestrial applications, and an initial demonstration with the telescope is planned for early 2020. With relatively minor changes to the KID design, it could also be optimized for astronomical applications.
