A low-power LGAD-timepix dosimeter for biological space radiation monitoring

ALCYONE, an EU-funded project under the Horizon Europe program, addresses the impact of prolonged space exposure on biological systems, which is a critical challenge for future long-duration space missions. The project focuses on the development of a miniaturized on-chip micro-incubator to monitor and control environmental conditions for four types of cell cultures. This contribution outlines the development of a high-resolution dosimeter based on fine-pitch trench-isolated LGADs, coupled with Timepix3 front-end electronics, for accurate radiation monitoring in both space and laboratory environments. The detector is seamlessly integrated into a compact, high-performance system-on-chip platform, enabling real-Time processing of radiation fluence and dose.
