סמינר בחלקיקים: COTS-Capsule – Apparatus for mitigating radiation induced faults in space systems

Abstract:

Operating electronic space systems in the space environment poses significant challenges due to continuous exposure to cosmic and solar radiation, which can lead to catastrophic single-events detrimental to the systems. Existing solutions for coping with such events are limited and often result in substantial cost penalties during the design and manufacturing phases of space systems. In this seminar, I will propose a mitigation strategy for catastrophic single-events that involves a non-intrusive apparatus. This apparatus facilitates the use of non-space-qualified electronics in space environments by singularly characterizing each impinging particle, thereby enabling the detection and mitigation of these events without altering the design of terrestrial electronics. I will discuss the development of custom-designed Scintillator-SiPM detectors for this apparatus, providing insights into their manufacturing process and testing procedures. Additionally, I will delve into the algorithms devised to accurately localize impinging particles and estimate deposited energy. Furthermore, I will present the design, manufacturing, and testing of a spaceborne experiment aimed at collecting data both on the ground and in space. Through simulations in a simulated space environment and empirical testing using measurements obtained from the "COTS-Capsule" spaceborne experiment, that was launched to the International Space Station as part of the “Rakia” mission, I will demonstrate the efficacy of our apparatus. By showcasing the results gathered in space, I will illustrate the feasibility of effectively operating commercial electronics in space when protected by our proposed apparatus. This advancement opens the door to integrating modern high-end components into space systems, thereby enhancing satellite performance while simultaneously reducing design and manufacturing costs and time.
