Characterization of a TES-based Anti-Coincidence Detector for Future Large Field-of-View X-ray Calorimetry Missions
Samuel V. Hull, Joseph S. Adams, Simon R. Bandler +22
Microcalorimeter instruments aboard future X-ray observatories will require an anti-coincidence (anti-co) detector to veto charged particle events and reduce the non-X-ray backgrou…
The X-ray Integral Field Unit at the end of the Athena reformulation phase
Philippe Peille, Didier Barret, Edoardo Cucchetti +279
The Athena mission entered a redefinition phase in July 2022, driven by the imperative to reduce the mission cost at completion for the European Space Agency below an acceptable ta…
System performance of a cryogenic test-bed for the time-division multiplexing readout for NewAthena X-IFU
Davide Vaccaro, Jan van der Kuur, Paul van der Hulst +23
The X-ray Integral Field Unit (X-IFU) is an instrument of ESA's future NewAthena space observatory, with the goal to provide high-energy resolution ( 4 eV at X-ray energies up t…
A 50 mK test bench for demonstration of the readout chain of Athena/X-IFU
Florent Castellani, Sophie Beaumont, François Pajot +22
The X-IFU (X-ray Integral Field Unit) onboard the large ESA mission Athena (Advanced Telescope for High ENergy Astrophysics), planned to be launched in the mid 2030s, will be a cry…
The Athena X-ray Integral Field Unit: a consolidated design for the system requirement review of the preliminary definition phase
Didier Barret, Vincent Albouys, Jan-Willem den Herder +296
The Athena X-ray Integral Unit (X-IFU) is the high resolution X-ray spectrometer, studied since 2015 for flying in the mid-30s on the Athena space X-ray Observatory, a versatile ob…
Optimal Filtering of Overlapped Pulses in Microcalorimeter Data
Dallas Wulf, Felix Jaeckel, Dan McCammon +2
Here we present a general algorithm for processing microcalorimeter data with special applicability to data with high photon count rates. Conventional optimal filtering, which has…
Progress in the development of frequency domain multiplexing for the X-ray Integral Field Unit on board the Athena mission
H. Akamatsu, L. Gottardi, J. van der Kuur +11
Frequency domain multiplexing (FDM) is the baseline readout system for the X-ray Integral Field Unit (X-IFU) on board the Athena mission. Under the FDM scheme, TESs are coupled to…
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 +11
We are developing the frequency domain multiplexing (FDM) read-out of transition-edge sensor (TES) microcalorimeters for the X-ray Integral Field Unit (X-IFU) instrument on board o…
Proximity Effects and Nonequilibrium Superconductivity in Transition-Edge Sensors
John E. Sadleir, Stephen J. Smith, Ian K. Robinson +5
We have recently shown that normal-metal/superconductor (N/S) bilayer TESs (superconducting Transition-Edge Sensors) exhibit weak-link behavior.1 Here we extend our understanding t…
Science Objectives for an X-Ray Microcalorimeter Observing the Sun
J. Martin Laming, J. Adams, D. Alexander +57
We present the science case for a broadband X-ray imager with high-resolution spectroscopy, including simulations of X-ray spectral diagnostics of both active regions and solar fla…
Longitudinal Proximity Effects in Superconducting Transition-Edge Sensors
John E. Sadleir, Stephen J. Smith, Simon R. Bandler +2
We have found experimentally that the critical current of a square superconducting transition-edge sensor (TES) depends exponentially upon the side length L and the square root of…
