URANOS v1.0 – the Ultra Rapid Adaptable Neutron-Only Simulation for Environmental Research

Abstract. The understanding of neutron transport by Monte Carlo simulations led to major advancements towards precise interpretation measurements. URANOS (Ultra Rapid Neutron-Only Simulation) is a free software package which has been developed in the last few years cooperation with particle physics and environmental sciences, specifically for purposes cosmic-ray sensing (CRNS). Its versatile user interface input/output scheme tailored CRNS applications offers hydrologists straightforward access model individual scenarios directly perform advanced calculations. geometry can be modeled layer-wise, whereas each layer voxel extruded using two-dimensional map from pixel images representing predefined materials allowing construction objects on basis graphics without three-dimensional editor. It furthermore features spectra detector configurations also allows replication important site characteristics study areas – small pond catchment scale. simulation thereby gives answers questions like location do neutrons originate? How they propagate sensor? What neutron's response certain changes? In recent years, successfully employed number studies, example, calculate footprint, signals complex geometries mobile roads, urban environments snow patterns.
