A joint Brookhaven National Laboratory-Oak Ridge National Laboratory International Workshop on Neutron Scattering Instrumentation was held at the Garden Plaza Hotel in Oak Ridge from June 5–7, 1989. The workshop, which was co-Ehaired by John Axe (BNL) and John Hayter (ORNL), was sponsored by the Division of Materials Sciences of the US Department of Energy. About 50 neutron scattering instrumentation experts from 19 laboratories in 8 countries attended. The purpose of the workshop was to review the status and limitations of current neutron scattering instrumentation, to discuss andexchange plansfor new instruments, and to stimulate thinking about innovative instrumentation concepts to meet the needs of the US neutron scattering community into the 1990's and beyond. In particular, the findings of the workshop will be used in planning instrument initiatives at the current high-flux reactors HFBR and HFIR and, in the long term, at the proposed Advanced Neutron Source (ANS) at Oak Ridge.
