The kilopixel array pathfinder project (KAPPa), a 16-pixel integrated heterodyne focal plane array — Characterization of the single pixel prototype


We report on the laboratory testing of KAPPa, a 16-pixel proof-of-concept array to enable the creation THz imaging spectrometer with -1000 pixels. Creating an array an order of magnitude larger than the existing state of the art of 64 pixels requires a simple and robust design as well as improvements to mixer selection, testing, and assembly. We present the characterization of the single pixel prototype, capable of housing an electromagnet or permanent magnet to suppress Josephson noise. We also present the current 16-pixel array design. This design continually evolves during single pixel testing.
