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…
Josephson effects in an alternating current biased transition edge sensor
Luciano Gottardi, Alex Kozorezov, Hiroki Akamatsu +10
We report the experimental evidence of the ac Josephson effect in a transition edge sensor (TES) operating in a frequency domain multiplexer and biased by ac voltage at MHz frequen…
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…
