User requirements as they impact spallation neutron source design

Experiments completed with the existing sources worldwide have shown that much good work can be done with present flux levels. In many cases the urgent need is for long-term stable running conditions. After this has been achieved there will be further requests for higher power levels, but again long-term stable running conditions will be emphasized as crucial to many experiments. In addition, many users work in other areas of physics and different disciplines and are not used to the problems of working in a high-energy physics environment. They need user friendly facilities and support services. Such services will also increase the productivity of all users and, therefore, should be regarded as essential. The points made above require the continuous attention of administrators and managers and should be given priority over any features that have been introduced for administrative or managerial convenience
