The new cryogenic silicon monolithic micro-bridged AntiCoincidence detector for the X-IFU of ATHENA

摘要

The new monolithic micro-bridged Cryogenic Anticoincidence for the X-IFU instrument of ATHENA has been designed. It is a single pixel made of silicon with Ir-Au TES array that respond to all the requirements of the recently closed design review phase. It is the natural prosecutor of the previous version without micromachined bridges (pre-demonstration model) It has shape has been fully characterized and its data were used to improve the new design. In this paper, we report the overview of this work of fabrication test and design. A preliminary delivery test with 60 keV gamma ray is also described.
