Towards Low-Energy Electron High-Resolution Spectroscopy with Transition-Edge Sensors

R. Ammendola, A. Apponi, G. Benato +62

We present a study of the energy resolution of transition-edge sensors (TESs) for the detection of electrons in the 100 eV kinetic energy range. The TES is a Ti-Au bilayer with an…

The TES-based Cryogenic AntiCoincidence Detector of ATHENA X-IFU: Validation of the thermal end-to-end simulator towards the updated Demonstration Model (DM 1.1)

Matteo D'Andrea, Claudio Macculi, Simone Lotti +13

The Cryogenic AntiCoincidence Detector (CryoAC) is a key element of the X-ray Integral Field Unit (X-IFU) on board the future ATHENA X-ray observatory. It is a TES-based detector d…
