Title: Helium generation in fusion reactor materials

Abstract

During this report period a topical report entitled A Neutron Fluence Map for the Rotating Target Neutron Source, (AI-ERDA-13188) was completed and distributed. The report inluded new 14.8-MeV neutron cross section data for the Ni, Nb, and Au dosimetry reactions. These results are summarized. A description is given of the preliminary analysis of wire rings included in the irradiation capsule for helium accumulation fluence dosimetry. The results show non-uniformities in the neutron fluence distribution characterizing this irradiation, and point out the value of helium accumulation fluence dosimetry for characterizing high energy (approx. 5 to 30 MeV) neutron fields. The helium accumulation fluence data are being used to adjust the neutron fluence map for calculation of final helium generation cross sections from the other RTNS-irradiated pure element specimens.
