Abstract

While nuclear fission research reactors as sources of a high thermal flux have more or less reached their limits as imposed by power density in the core, accelerator based spallation neutron sources are still largely a matter of development. The low power facilities (less than 0.5 MW of beam power) built and operated so far have successfully demonstrated the potential of the technique and have triggered several proposals for new installations in the medium power range (0.5 to 5 MW). Most of these projects relate to pulsed neutron sources which have enhanced capabilities for many techniques of neutron scattering work but are less suitable for other applications which require a high time average flux as provided by cw-sources. In both cases there is a rather limited data base on the radiation effects and other parameters affecting the design and life time of their targets. At present, there is one new spallation neutron source under construction, SINQ in Switzerland. It is expected to deliver neutrons as of 1996 and, apart from neutron scattering experiments with thermal and cold neutrons, it will also provide isotope production and activation analysis capabilities as well as opportunities for target development work.
