The international thematic school on “Crystallography and Neutrons” was organized in order to celebrate the International Year of Crystallography in 2014, under the patronage of the “Société Française de la Neutronique” (SFN) with the support of the CNRS and the European neutron facilities network NMI3. The school took place in September 2014 in Oléron, France, as first part of the “22ème Journées de la Neutronique” (JDN22). The school gathered participants from European countries and therefore the lectures were given in English. It intended to promote cooperation and networking among users of large scale facilities with researchers involved in the field of Crystallography.
