Experimental absorption corrections for highly absorbing europium compounds in powder neutron diffraction

Journal of Applied Crystallography, EarlyView.
An experimental method for absorption correction of powder samples containing highly neutron absorbing elements is reported.For materials with strong neutron absorption, such as europium (Eu), the absorption correction method is important but difficult to manage. This is because Eu has a strong isotope dependence. The energy dependence of absorption is

Towards improving the PF1B beamline McStas model through simulations of a beam characterization experiment

Journal of Applied Crystallography, EarlyView.
McStas simulations of a recent time‐of‐flight characterization of the PF1B instrument at the Institut Laue–Langevin show good agreement with the current beamline model, while also highlighting opportunities to refine some parameters of the simulation using the collected time‐of‐flight data as a benchmark.The PF1B instrument at the Institut Laue ...
