Solid state sensors have become the standard choice for radiation measurements in space since the early 2000s. Leveraging the development of tracking detectors for collider experiments, large area silicon strip systems have been designed and successfully operated in space in several astro-particle missions. With the multiplication of flight opportunities offered by the new space economy, the...

Silicon microstrip (Si-µstrip) sensors are employed in most of current space detector tracking systems for charged cosmic-rays, such as the DAMPE satellite detector or the AMS-02 detector onboard the ISS. As they allow for large-area coverage with contained electronic channels and power consumptions, they are ideal sensors for high-energy physics applications in space-borne instrumentation,...

Charge identification is a challenging task in space-based cosmic-ray (CR) experiments. This is due to the wide dynamic range required to identify CR elements, including heavy nuclei. Additionally, back-scattered radiation from the calorimeter degrades the charge resolution when it hits the same detector element traversed by the cosmic ray, hindering a correct identification of the cosmic...

Low Gain Avalanche Diodes (LGADs) are silicon detectors that use the impact ionization process to achieve gain values of about O(10) and timing resolution of 30 ps for Minimum Ionizing Particles. In High Energy Physics, the state of the art LGADs used for timing layers have an active thickness of 50 μm and a channel size in the order of O(1 mm2). Space based experiments could benefit from a...
