X-IFU warm front-end electronics demonstrator model

On demand | Presented live 17 June 2024

Abstract

The ATHENA space mission will be the next generation X-ray observatory. The X-ray integral field unit (X-IFU) is ATHENA’s cryogenic spectro-imager, observing the sky with thousands of superconducting microcalorimeters. The detectors are based on transition edge sensors (TES) in time-division multiplexing (TDM). A warm front-end electronics (WFEE) demonstrator model (DM) has been developed for the low noise biasing and readout of X-IFU’s cryogenic detection chain. After extensive testing, it has been delivered to the French space agency (CNES) for integration in the full detection chain DM. The WFEE DM is capable of reading out and biasing 8 TDM channels. Different configurations were chosen for some of the channels in order to find the best performance after testing of the whole demonstrator readout chain. Design and measured noise performances are discussed.
