(author), Morozov, Dmitry (author), Trappe, Neil A. (author), Doherty, Stephen (author)The next generation of far infrared space observatories will require extremely sensitive detectors that can be realized only by combining extremely low intrinsic noise with high optical efficiency. We have measured the broad-band optical response of ultra-sensitive transtion edge sensor (TES) bolometers (NEP ≈ 2 aW / Hz) in the 30-60-μm band...journal article 2016

(author)We have constructed a test facility for characterizing the focal plane arrays of SAFARI, the far-infrared imaging spectrometer for the SPICA satellite. SAFARI’s three bolometer arrays are populated with extremely sensitive (NEP ? 2 × 10?19 W/? Hz) transition edge sensors with a transition temperature close to 100 mK. The extreme sensitivity and...journal article 2012
