Journal ArticleDOI
High aspect ratio transition edge sensors for x-ray spectrometry
M. de Wit,Luciano Gottardi,Emanuele Taralli,Kenichiro Nagayoshi,Marcel L. Ridder,Hiroki Akamatsu,Marcel P. Bruijn,M. D'Andrea,J. van der Kuur,K. Ravensberg,D. Vaccaro,S. Visser,J. R. Gao,J. R. Gao,J. W. den Herder +14 more
TL;DR: In this article, the authors present a characterization of a transition edge sensor (TES) array containing five different device geometries, with aspect ratios ranging from 1:2 up to 1:6.
Journal ArticleDOI
Design and validation of a large-format transition edge sensor array magnetic shielding system for space application.
Anne Bergen,H. van Weers,C. Bruineman,Marc Dhalle,Hendrikus J.G. Krooshoop,H.J.M. ter Brake,K. Ravensberg,Brian Jackson,C. K. Wafelbakker +8 more
TL;DR: The development and the experimental validation of a cryogenic magnetic shielding system for transition edge sensor based space detector arrays is described, with the system's measured on-axis shielding factor well exceeding the requirement of the envisaged missions.
Proceedings ArticleDOI
Development of frequency domain multiplexing for the X-ray Integral Field Unit (X-IFU) on the Athena
Hiroki Akamatsu,Luciano Gottardi,Jan van der Kuur,Cor P. de Vries,K. Ravensberg,J. S. Adams,Simon R. Bandler,Marcel P. Bruijn,James A. Chervenak,Caroline A. Kilbourne,Mikko Kiviranta,A. J. van der Linden,Brian Jackson,Stephen J. Smith +13 more
TL;DR: In this article, the frequency domain multiplexing (FDM) readout of transition-edge sensor (TES) microcalorimeters for the X-ray Integral Field Unit (X-IFU) instrument on board of the future European X-Ray observatory Athena is presented.
Journal ArticleDOI
Progress in the Development of Frequency-Domain Multiplexing for the X-ray Integral Field Unit on Board the Athena Mission
Hiroki Akamatsu,Luciano Gottardi,J. van der Kuur,C. P. de Vries,Marcel P. Bruijn,James A. Chervenak,Mikko Kiviranta,A. J. van den Linden,Brian Jackson,Antoine R. Miniussi,K. Ravensberg,Kazuhiro Sakai,Stephen J. Smith,Nicholas A. Wakeham +13 more
TL;DR: In this paper, the authors used high-quality-factor LC filters and room-temperature electronics developed at SRON and low-noise two-stage SQUID amplifiers provided by VTT for the FDM readout of Mo/Au TES calorimeters with Au/Bi absorbers.
