Abstract/Contents

Abstract: Ground based telescopes operating in the millimeter wave regime are attempting to image the sky with increasing sensitivity and depth by employing larger arrays of cryogenically cooled detectors. However, the increase in aperture is accompanied by a corresponding increase in the infrared (IR) loading. This poses a significant challenge for the cryogenic system. BICEP3 met this challenge by developing laser etching as a fabrication technique for producing large aperture metal-mesh infrared filters. Because metal-mesh filters are crucial to the heat load balance of the cryogenic system, we conducted a systematic investigation into the quality, repeatability of production and improvement in the yield of filters.
