X-IFU Consortium meeting #20

Last week we had the 20th X-IFU Consortium meeting at IRAP in an hybrid format. A very successful gathering, in part to celebrate the success of the ESA led intermediate review of newAthena, indicating that we are on track for the planned mission adoption in 2027. On-going technology demonstration activities were extensively presented during the meeting. The meeting gathered around 140 attendees at the peak.

Understanding TES Performance in Modified Bias Circuits for X-IFU Multiplexed Readout

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). […]

Successful coupling of the X-IFU Warm Front-End Electronics demonstrator at SRON

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 first test of the Cryogenic AntiCoincidence detector (CryoAC) inside the X-IFU Demonstration Model 1.1 has been successfully completed
