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…
Characterisation of a TES-Based X-ray Microcalorimeter in the Energy Range from 150 to 1800 eV Using an Adiabatic Demagnetisation Refrigerator
Luciano Gottardi, Yoh Takei, Jan van der Kuur +8
We characterised a TES-based X-ray microcalorimeter in an adiabatic demagnetisation refrigerator (ADR) using synchrotron radiation. The detector response and energy resolution was…
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…
