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…
