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…
A multiplexer for the ac/dc characterization of TES based bolometers and microcalorimeters
Luciano Gottardi, Hiroki Akamatsu, Marcel Bruijn +9
At SRON we are developing the Frequency Domain Multiplexing (FDM) for the read-out of the TES-based detector array for the future infrared and X-ray space mission. We describe the…
AC bias characterization of low noise bolometers for SAFARI using an Open-Loop Frequency Domain SQUID-based multiplexer operating between 1 and 5 MHz
Luciano Gottardi, Marcel Bruijn, Jan-R. Gao +8
SRON is developing the Frequency Domain Multiplexing (FDM) readout and the ultra low NEP TES bolometers array for the infrared spectrometer SAFARI on board of the Japanese space mi…
Weak-Link Phenomena in AC-Biased Transition Edge Sensors
Luciano Gottardi, Hiroki Akamatsu, Marcel Bruijn +9
It has been recently demonstrated that superconducting transition edge sensors (TESs) behave as weak-links due to longitudinally induced superconductivity from the leads with highe…
