MRADSIM (Matter-RADiation Interactions SIMulations)

Matter-RADiation interaction SIMulation (MRADSIM) is an innovative modular software toolkit developed to simulate the effects of radiation on electronic components, human beings and various materials. It incorporates innovative features aimed at enhancing parametric precision, reducing computational time, and introducing supplementary functions for tailored calculations across diverse applications including the applications required for space missions. Notably, MRADSIM is distinguished as the pioneering simulation toolkit to integrate cutting-edge Artificial Intelligence and Machine Learning (AI/ML) algorithms, with the primary objective of effectively recognizing potential radiation-induced issues and facilitating the implementation of mitigation strategies to avert catastrophic failures in mission-critical systems, whether terrestrial or space-based. The distinctive attributes of MRADSIM, coupled with its early adoption by researchers from the National Institute for Nuclear Physics of Italy (INFN), significantly contribute to the toolkits added value.

UV Irradiation Facility for Solar Effects Simulations

We describe an experimental setup developed aiming to irradiate samples under UV radiation for accelerated test for solar effects according to the relevant ECSS-ESA standards. This facility has been already used for projects belonging to large space programs (Cosmic Vision, Artes) for simulations up to 3500 equivalent sun hours. In particular, we detail the calculation of the UV dose delivered by Sun, the calibration of the detectors, the spatial distribution of the UV radiation on samples, the remote control of both samples temperature and lamp radiation, the samples heat dissipation and operation in a helium atmosphere.

Low Energy, High Flux, Uniform and Large Field Size Electron Beam Facility

Materials to be deployed in space applications have to undergo a variety of different test scenarios, simulating actual space conditions. Among these materials solar photovoltaic cells, optics, meta-materials and more will be directly exposed to space radiation and must be tested accordingly. From the design phase of such target materials to the final production, it is important to obtain information about their behavior and performance in defined irradiation scenarios and qualify them following the directions of relevant ECSS/ESA standards. An excellent method to cover part of these tests in a laboratory scale is the high-flux, high-fluence electron irradiation with the help of industrial electron beam generators. The present collaboration has developed different irradiation test setups and procedures, adapted to the existing electron beam generators at IPF in Dresden, Germany covering an energy range between 100 keV to 1.5 MeV. The test setups, aiming for high electron flux, uniform and large irradiation field sizes, and their capabilities for use in irradiation qualification tests for space applications are described in this paper.
