Event details

Neutron scattering is a uniquely powerful technique for locating hydrogen and other low-Z atoms within solids, for the measurement of atomic thermal motion and disorder, for the determination of magnetic ordering and for studies of collective excitations. Until 1990 these advantages were not available for studies at high-pressure because neutron pressure cells were not able to achieve pressures greater than ~3 GPa. In my talk I will describe the development of a novel pressure cell -- The Paris-Edinburgh cell -- which has now increased the pressure range by a full order of magnitude to 30 GPa. I will illustrate the new information that this has provided with studies carried out using the cell.

This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
