The Kiel/Berlin high-pressure cells for neutron powder diffraction

A heatable high-pressure neutron powder diffraction cell has been developed on the basis of the well-known McWhan piston-cylinder type, Ir operates up to 700 K and 15 kbar, simultaneously. The cell has successfully been applied for the investigation of p/T phase diagrams as well as for standard high-pressure work. In order to extend the accessible range of pressure and temperature, a new cell has been designed. We hope to attain at least 35 kbar and 700-1000 K with this new cell.
