Influence of path length on wavelength dependent transmission corrections for hydrogenous materials

Abstract: Diffraction from hydrogenous materials is complicated by its large incoherent scattering contribution. For many materials, deuteration before performing experiments is the solution. For many systems this is not possible, due to incomplete deuteration, cost and/or changes to the structure and/or phase transitions that are of interest. For TOF methods, the situation is further complicated by the energy dependence of the incoherent scattering cross-section, meaning that both transmission and multiple scattering corrections are energy dependent. This proposal continues on the previous work (RB1810041) to investigate the effects of path length using powders and a well defined H-content liquid for absolute comparisons, which we were unable to attempt due to time constraints. The aim is to generate empirical curves for data correction of TOF diffraction data at ISIS and other pulsed sources.
