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…
Developments on frequency domain multiplexing readout for large arrays of transition-edge sensor X-ray micro-calorimeters
D. Vaccaro, H. Akamatsu, L. Gottardi +8
At SRON we have been developing X-ray TES micro-calorimeters as backup technology for the X-ray Integral Field Unit (X-IFU) of the Athena mission, demonstrating excellent resolving…
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…
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…
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…
Thermal crosstalk of X-ray transition-edge sensor micro-calorimeters under frequency domain multiplexing readout
Davide Vaccaro, Hiroki Akamatsu, Marcel P. Bruijn +12
We have measured and characterized the thermal crosstalk in two different arrays of transition-edge sensor (TES) X-ray micro-calorimeters with frequency-domain multiplexing (FDM) r…
