Gas pressure cells for elastic and inelastic neutron scattering

Gas pressure cells techniques are well adapted to neutron scattering applications. They can routinely be used at least up to pressures of 0.5 GPa in a wide temperature range, they allow for an accurate pressure control and also provide the chemical activity for the study of materials where the gas is not only the pressure transmitting medium but also a chemical constituent of the system. We present some of the gas pressure cells which were developed by us for specific needs and discuss their design and performance.
