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…
Study of the dependency on magnetic field and bias voltage of an AC-biased TES microcalorimeter
Luciano Gottardi, James Adams, Catherine Bailey +15
At SRON we are studying the performance of a Goddard Space Flight Center single pixel TES microcalorimeter operated in an AC bias configuration. For x-ray photons at 6 keV the pixe…
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…
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…
