Advancing Particle Detector Technologies for Space Applications in Astroparticle Physics

Astroparticle physics has been experiencing rapid growth, particularly in the era of multi-messenger observations, which has led to an increasing demand for particle detection experiments suitable for space applications. The surge in space missions dedicated to monitoring celestial events, exemplified by Fermi and Integral, highlights the necessity for efficient and versatile experimental setups. Additionally, the scientific community growing interest in space weather observations, as exemplified by projects like CSES and NUSES, underscores the need for advanced monitoring capabilities of Earth phenomena from space. A key focus in astroparticle research revolves around the investigation of dark matter, which has spurred the development of novel astroparticle experiments on satellites like AMS, PAMELA, HERD, and ALADINO. Consequently, the field of astrophysics is striving to design complex systems for detecting photon polarization in space, as demonstrated by projects like IXPE. The thesis addresses three key aspects in advancing particle detector technology for space experiments. Firstly, it introduces an innovative approach to connect Monolithic Active Pixel Sensors (MAPS) with their electronics, ensuring low mass budget and flexible solutions, which are vital considerations in space missions. Secondly, the study explores the utility of Lutetium-Yttrium Oxyorthosilicate (LYSO) detectors for space applications, encompassing the detection of charged particles and Gamma-Ray Bursts (GRBs). Finally, the thesis proposes a novel microfabrication technique for Gas Electron Multipliers (GEMs) to detect photon polarization in space. By addressing the need for advancements in particle detector technology and introducing innovative methodologies, this research aims to enhance the efficiency and applicability of such technologies in space-based astroparticle experiments.
