For the future fusion materials development program it is necessary to have
a dedicated high intensity neutron source available. IFMIF, an accelerator
-based intense D-LI neutron source that produces neutrons with a suitable e
nergy spectrum at high intensity and sufficient irradiation volume, is a ne
ar term feasible concept which fulfills all essential requirements of the f
usion materials development program defined by the users community. IFMIF p
erforms all necessary kinds of material tests with high flexibility in the
materials test matrix and the very attractive capability of accelerated irr
adiations up to about 50 dpa per full power year. (C) 2000 Elsevier Science
