ISIS is the world's most intense pulsed neutron source and is Europe's only such facility. It is instrumented with high-quality spectrometers which access the finest resolutions and the
highest energy transfers, the shortest lattice parameters and the largest structural units. The spectrometers are under constant upgrade and the instrument suite is steadily expanding. Pulsed sources are now accepted world-wide as offering the greatest potential for the future development of neutron scattering and the proposed European Spallation Source will maintain Europe's
undisputed lead well into the 21st century. ISIS is 80% U.K. funded but has a number of international partners within Europe and beyond. It has operated a full international user programme for ten years with a well-developed infrastructure for all aspects of user liaison. Great emphasis is placed upon personal user support and training. The HCM programme at ISIS has allowed wide European access to non-partner countries as well as enhancing access to European partners. Particular effort has been made to attract users from all European countries. The present proposal requests 120 days access per year to ISIS, which represents -6% of the programme, together with funding for new-user training courses.
