| Abstract | URANOS is a newly developed threedimensional neutron transport Monte-Carlo code for thermal to fast energies. It was originally developed for the CASCADE detector. The purpose of the simulation is to merge a computationally efficient engine with an intuitive graphical user interface addressing solutions for small to medium-sized projects. It employs a ray-casting approach with a voxel engine. The geometry is extruded layer-by-layer from a pixel matrix of material-specific numbers. The input files consist of a series of images or matrices, while all other parameters, including the configuration of predefined sources, can be modified through the graphical interface. The scattering kernel contains the handling of elastic and inelastic collisions, as well as absorption and absorption-related interactions such as evaporation. Cross sections, energy and angular distributions are extracted from evaluated data bases. To simulate boron-lined detectors an additional model predicts the conversion ion transport by calculating the energy loss in the boron film and its subsequent gaseous layer. Calculating longitudinal and transversal diffusion the engine then projects the electron track onto a readout unit. URANOS is provided as an open-source software package and can be used to simulate the response function of thermal or epithermal neutron detectors, evaluate the neutron flux in small-scale laboratory setups and especially conduct transport studies of cosmic-ray induced neutrons in environmental applications. It offers an easy accessibility and comparably simple interface capable of handling complex geometries. URANOS therefore offers possibilities to understand and simulate the neutron environment at instruments, which would otherwise require extensive modeling and training on dedicated packages. |
