Scientific opportunities with advanced facilities for neutron scattering Summary of a workshop held at Shelter Island, New York, USA October 23-26, 1984

This article presents a summary of a Workshop held in October 1984 to discuss scientific opportunities in the field of neutron scattering. Introductory material summarizes both the goals of the Workshop and makes a case for more intense sources of neutrons. This section is followed by the recommendations of the Workshop. None of this material requires a detailed knowledge of neutron scattering. The technical part of the paper follows and consists of ten brief reports reflecting various aspects of neutron scattering, and the new opportunities that would be available if more intense sources were constructed. Each report also compares the opportunities with a new 5 × 10 ¹⁵ n cm ^-2 s ^-1 steady state source and with a new 10 ¹⁷ n cm ^-2 s ^-1 peak flux spallation source. Such comparisons are made across all fields of science in which neutron scattering is applied.
