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…
Performance of an X-ray single pixel TES microcalorimeter under DC and AC biasing
Luciano Gottardi, Jan van der Kuur, Piet A. J. de Korte +7
We are developing Frequency Domain Multiplexing (FDM) for the read-out of TES imaging microcalorimeter arrays for future X-ray missions like IXO. In the FDMconfiguration the TES is…
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…
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…
