  2. Motivation: Data Needs • IFMIF (International Fusion Material Irradiation Facility) D-Li neutron source for testing fusion reactor candidate materials • General purpose : Activation/transmutation data library • [U. Fischer: "Nuclear Data Libraries for Advanced Systems: Fusion Devices“, Nov 2007, IAEA, Vienna] • Urgent need for qualified IFMIF reference data library • IEAF/EAF : (n, p, d), to be further developed, improved and validated • Cross section measurements & calculations required for neutrons (E >20 MeV): Cr, Co, V, W, Ta, Pb, Bi, Au, Mn deuterons (E ~ 60 MeV): Al, Cu,Nb, Co protons (E < 12 MeV): Cu, Al, Nb, Ta, W, Au, Pb • Evaluations (n, p, d) to be further developed, improved and validated • Reliable gas production cross-section data (H, He) • Dosimetry data file to be developed for E > 20 MeV (IRDF) • Surrogate reactions • Complementary analysis for (d,f) cross section evaluation Phys.
