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 TDM test-bed with long flex harness towards the new X-IFU FPA-DM
D. Vaccaro, M. de Wit, J. van der Kuur +17
SRON (Netherlands Institute for Space Research) is developing the Focal Plane Assembly (FPA) for Athena X-IFU, whose Demonstration Model (DM) will use for the first time a time dom…
Frequency domain multiplexing readout for large arrays of transition-edge sensors
Davide Vaccaro, Hiroki Akamatsu, Luciano Gottardi +13
We report our most recent progress and demonstration of a frequency domain multiplexing (FDM) readout technology for transition-edge sensor (TES) arrays, both of which we have been…
Performance of the SRON Ti/Au Transition Edge Sensor X-ray Calorimeters
Martin de Wit, Luciano Gottardi, Kenichiro Nagayoshi +7
In the early 2030s, ESAs new X-ray observatory, Athena, is scheduled to be launched. It will carry two main instruments, one of which is the X-ray Integral Field Unit (X-IFU), an X…
Susceptibility study of TES micro-calorimeters for X-ray spectroscopy under FDM readout
Davide Vaccaro, Hiroki Akamatsu, Luciano Gottardi +15
We present a characterization of the sensitivity of TES X-ray micro-calorimeters to environmental conditions under frequency-domain multiplexing (FDM) readout. In the FDM scheme, e…
Mitigation of the Magnetic Field Susceptibility of Transition Edge Sensors using a Superconducting Groundplane
Martin de Wit, Luciano Gottardi, Marcel L. Ridder +7
Transition edge sensor (TES) microcalorimeters and bolometers are used for a variety of applications. The sensors are based on the steep temperature-dependent resistance of the nor…
