The SPIE meeting 2026 was the opportunity to present X-IFU as it stands today, as we move towards the start of the mission adoption process, to be concluded in June 2027. The overview presentation given by Philippe Peille (CNES, Instrument manager) showed the status of X-IFU, and presented all the demonstration activities that are on-going. […]
A recent paper by Smith et al., « Transition-edge sensor characteristics in a modified bias circuit for multiplexed readout, »has been accepted for publication in the IEEE Transactions on Applied Superconductivity. The work addresses an important aspect of X-IFU detector readout: the impact of incorporating a bypass resistor into the bias circuit used for time-division multiplexing (TDM). […]
A major milestone has been reached beginning of October 2025 in the development of the Warm Front-End Electronics (WFEE) for the ATHENA X-IFU detection chain with the successful coupling of WFEE demonstrator model 2 (DM2) during the Focal Plane Assembly (FPA) DM1.1 test campaign at SRON (Space Research Organisation Netherlands). The WFEE, developed by APC […]

The X-ray Integral Field Unit (X-IFU) is the cryogenic instrument onboard NewAthena mission. In the late 30s, it will transform our understanding of the hottest components and the most energetic phenomena in […]
SRON is responsible for building the camera for the X-IFU imaging spectrometer onboard the NewAthena X-ray space telescope. A latest Demonstration Model has now been successfully assembled in SRON’s cleanroom and is mounted into a cryogenic test setup which cools the detector stage to a temperature of 50 milliKelvin. In the late 30s , ESA […]
The paper titled « Wide Band Transmission Response of the Filters for the X-IFU Detector of the Athena Observatory », presented at ICSO 2024, investigates the optical blocking filters used in the X-ray Integral Field Unit (X-IFU) aboard the Athena space observatory. These filters, composed of polyimide films coated with aluminum, are designed to block out-of-band radiation—such as […]
The year 2023 has just come to an end. 2024 opens with new perspectives for the X-IFU project and for the Consortium. On behalf of the X-IFU Consortium, we would like to take this opportunity to thank you for your confidence. We wish you all a very happy and successful new year!
The Warm Front-End Electronics (WFEE) Demonstrator Model was delivered to CNES on November 6, 7 and 8, 2023. Supply of the WFEE has been the responsibility of the Astroparticle and Cosmology (APC) laboratory.
On Wednesday November 8, 2023, ESA’s Science Programme Committee (SPC) formally and unanimously approved the restart of industrial studies for the Athena mission, still considered as a flagship mission.
