High-sensitivity transition-edge-sensed bolometers: improved speed and characterization with AC and DC bias
Logan Foote, Michael D. Audley, Charles +12
We report on efforts to improve the speed of low-G far-infrared transition-edged-sensed bolometers. We use a fabrication process that does not require any dry etch steps to reduce…
Simulation and Measurement of Out-of-Band Resonances for the FDM Readout of a TES Bolometer
Amin Aminaei, Hiroki Akamatsu, Ad Nieuwenhuizen +10
With applications in cosmology, infrared astronomy and CMB survey, frequency-division multiplexing (FDM) proved to be a viable readout for transition-edge sensors (TES). We investi…
The SAFARI Detector System
Michael D. Audley, Gert de Lange, Jian-Rong Gao +9
We give an overview of the baseline detector system for SAFARI, the prime focal-plane instrument on board the proposed space infrared observatory, SPICA. SAFARI's detectors are bas…
SPICA - a large cryogenic infrared space telescope Unveiling the obscured Universe
P. R. Roelfsema, H. Shibai, L. Armus +66
Measurements in the infrared wavelength domain allow us to assess directly the physical state and energy balance of cool matter in space, thus enabling the detailed study of the va…
Optical performance of prototype horn-coupled TES bolometer arrays for SAFARI
Michael D. Audley, Gert de Lange, Jian-Rong Gao +3
The SAFARI Detector Test Facility is an ultra-low background optical testbed for characterizing ultra-sensitive prototype horn-coupled TES bolmeters for SAFARI, the grating spectro…
Optical performance of an ultra-sensitive horn-coupled transition-edge-sensor bolometer with hemispherical backshort in the far infrared
Michael D. Audley, Gert de Lange, Jian-Rong Gao +7
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 op…
