High-pressure cell for in situ neutron studies of hydrogen storage materials


A high- pressure cell for neutron experiments was developed at Helmholtz-Zentrum Geesthacht (HZG). This cell is designed for the investigation of hydrogen storage materials at pressures up to 700 bar and temperatures up to 500°C. The idea is to have a prototype cell for different neutron scattering methods (diffraction, time- of-flight spectroscopy and small-angle neutron scattering). In this work, we discuss the development and the current state of the high- pressure cell. Furthermore, the deployment of the cell for in situ small-angle neutron scattering measurements on 6Mg(NH2 )2 + 9LiH + LiBH4 (6:9:1) at the instrument SANS-1 at Heinz Maier-Leibnitz Zentrum (MLZ) is demonstrated.
