This repository contains code for the NCrystal plugin named SANSND, which implement Small Angles Neutron Scattering for NanoDiamonds.
This plugin is mainly based on the work of José Ignacio Marquez Damian, Monte Carlo Simulation Scientist at ESS Spallation Physics, who implemented Nanodiamond support in MCNP and PHITS.
It is currently under development and not ready for general usage
The simple model implemented here has its basis in the SANS structure factor measured by Teshigawara et al. and combines it with a scattering kernel for bulk diamond computed from DFT as explained by Granada et al.. The structure factor in the Teshigawara paper is fitted by a power-exponential law, which is then further simplified into a piecewise power fit.
