Signal readout for Transition-Edge Sensor X-ray imaging spectrometers
H. Akamatsu, W. B. Doriese, J. A. B. Mates +1
Arrays of low-temperature microcalorimeters provide a promising technology for X-ray astrophysics: the imaging spectrometer. A camera with at least several thousand pixels, each of…
Demonstration of MHz frequency domain multiplexing readout of 37 transition edge sensors for high-resolution x-ray imaging spectrometers
H. Akamatsu, D. Vaccaro, L. Gottardi +22
We report on the development and demonstration of a MHz frequency domain multiplexing (FDM) technology to read out arrays of cryogenic transition edge sensor (TES) X-ray microcalor…
Characterization of high aspect ratio TiAu TES X-ray microcalorimeters array using the X-IFU Frequency Domain Multiplexing readout
E. Taralli, L. Gottardi, K. Nagayoshi +7
We are developing X-ray microcalorimeters as a backup option for the baseline detectors in the X-IFU instrument on board the ATHENA space mission led by ESA and to be launched in t…
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…
