Abstract

Studies of astrophysical emission in the far-infrared and submillimeter require large arrays of detectors containing from hundreds to thousands of elements. A multiplexed readout is necessary for practical implementation of such arrays, and can be developed using SQUIDs, such that, e.g., a 32 x 32 array of bolometers can be read out using 100 wires than the - 2000 needed with a brute force expansion of existing arrays. These bolometer arrays are made by micromachining techniques, using superconducting transisition edge sensors as the thermistors. We describe the development of this multiplexed superconducting bolometer array architecture as a step toward will be used in the SAFIRE instrument on SOFIA instrument on SOFIA, and is a condidate for a wide variety of other spectroscopic and photometric instruments.
