ILL Science Council: Review of Powder Diffraction

updated 31 March 1999 

The workshop was held on Monday-Tuesday 22-23 March 1999 at ILL. The objectives of the review, and also the proposals for instrument improvements under the Millenium Programme were covered. A summary of the main conclusions has been prepared for the ILL Science Council by the Review Chairman, Charles de Novion, with a further account to be published in Neutron News. And here is a group photograph of participants enjoying the Grenoble sunshine !
