Simulation and Measurement of Out-of-Band Resonances for the FDM Readout of a TES Bolometer
Amin Aminaei, Hiroki Akamatsu, Ad Nieuwenhuizen +10
With applications in cosmology, infrared astronomy and CMB survey, frequency-division multiplexing (FDM) proved to be a viable readout for transition-edge sensors (TES). We investi…
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…
ATHENA X-IFU Demonstration Model: First joint operation of the main TES Array and its Cryogenic AntiCoincidence Detector (CryoAC)
M. D'Andrea, K. Ravensberg, A. Argan +28
The X-IFU is the cryogenic spectrometer onboard the future ATHENA X-ray observatory. It is based on a large array of TES microcalorimeters, which works in combination with a Cryoge…
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…
The Hot and Energetic Universe: The X-ray Integral Field Unit (X-IFU) for Athena+
D. Barret, J. W. den Herder, L. Piro +55
The Athena+ mission concept is designed to implement the Hot and Energetic Universe science theme submitted to the European Space Agency in response to the call for White Papers fo…
