abstract = {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.},
