Web pages on BCA site for 'in situ' diffraction

The scope for in situ diffraction experiments has increased enormously over recent years as more intense sources of X-rays and neutrons have enabled experiments to be carried out on smaller samples or faster transformations, or in environments with poor access to the probe. Pannetier and his colleagues are studying chemical and structural changes that occur inside a solid-state battery as it discharges and the cell reaction proceeds. Neutron diffraction provides a direct probe of these processes in real time in the chemical environment most relevant to the problem. A web page is being set up on the BCA web site to provide an information source on techniques and facilities, areas of activity and practitioners, for experts and would-be users. A. Harrison and K. Crennell are setting up a draft page at The page will focus initially on activities in the UK, concentrating on neutron diffraction and X-ray techniques, with links to the more specialized information held at the CLRC Lab by the ISIS Facility and the SRS Daresbury. In the future, the scope of the activities and practitioners will extend beyond the UK and may also include other structural probes such as EXAFS.
