TI  - Conceptual design of neutron imaging instruments for the High Brilliance Neutron Source

PY  - 2023
AB  - The High Brilliance Neutron Source (HBS) project aims to develop a High-Current Accelerator-driven Neutron Source (HiCANS) for neutron scattering, analytics, and imaging. Amongst the 25 instruments planned at HBS, there will be at least five different neutron imaging instruments: cold, diffractive, thermal, resonance/epithermal, and fast, covering the different neutron energy ranges.These neutron imaging instruments will have different sample positions, which can be selected to optimize the flux, collimation, spatial, wavelength, and time resolutions. Each of these positions will be best suited for studies considering the specific energy ranges to investigate hydrogen in metals, strain phase mapping studies in engineering and energy conversion processes, archeological characterization, automotive and aerospace applications, or battery processes.For the optimization of the required neutronic parameters, Monte Carlo simulations were performed, starting from the source and ending at the sample position. For the source simulations, the PHIT code was used, while VITESS and McStas performed the ray transport through the instrument. Also, an open-source code called KDSource was used to estimate the source distribution at a given point in the beam trajectory, and then resample new particles that respect the correlations of the original source.The objective of this work is the presentation of the conceptual design of these instruments, the procedure for the simulations, the principal parameters, and the potential capabilities.
