  2. Activation/transmutation data • General purpose neutron data library • Urgent need for qualified IFMIF reference data library • IEAF/EAF (n, p, d), to be further developed, improved and validated • Cross section measurements required for • neutrons (E >20 MeV): Cr, Co, V, W, Ta, Pb, Bi, Au, Mn • deuterons (E < 40 MeV): Cu,Al, Nb, • protons (E < 12 MeV): Cu, Al, Nb, Ta, W, Au, Pb • Validation experiments, to be extended/continued • Reliable gas production cross-section data (H, He) • Dosimetry data file to be developed for E > 20 MeV (IRDF) IFMIF Data Needs[U.
