Ground calibration plan for the Athena/X-IFU microcalorimeter spectrometer

Alexeï Molin, François Pajot, Marc Audard +24

The X-ray Integral Field Unit is the X-ray imaging spectrometer on-board one of ESA's next large missions, Athena. Athena is set to investigate the theme of the Hot and Energetic U…

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…

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…

The development of a testbed for the X-ray Interferometer mission

Roland den Hartog, Phil Uttley, Richard Willingale +3

An X-ray Interferometer (XRI) has recently been proposed as a theme for ESA's Voyage 2050 planning cycle, with the eventual goal to observe the X-ray sky with an unprecedented angu…

Frequency Shift Algorithm: Application to a Frequency-Domain Multiplexing Readout of X-ray Transition-Edge Sensor Microcalorimeters

D. Vaccaro, H. Akamatsu, J. van der Kuur +17

In the frequency-domain multiplexing (FDM) scheme, transition-edge sensors (TES) are individually coupled to superconducting LC filters and AC biased at MHz frequencies through a c…
