Energy dependent, sample transmission correction for time-of-flight diffraction data normalisation from hydrogenous materials

Abstract: Diffraction from hydrogenous materials is complicated by the large incoherent scattering contribution from hydrogen. For many materials the solution is to deuterate before performing neutron experiments. However, for many materials this is not possible, due to incomplete deuteration, cost and/or the fact that deuteration changes the structure and phase transitions that are of interest. For time of flight methods, the situation is further complicated by the fact that the hydrogen incoherent scattering cross section is energy dependent, therefore, sample transmission is energy dependent. This proposal aims to investigate and quantify the effect for well known hydrogenous materials as a function of sample path length, temperature and hydrogen content to generate empirical curve(s) that can be used in reduction of hydrogenous diffraction data for the suite of instruments at ISIS.
