Effect of 1.9-MeV electron irradiation on characteristics of reactively-pressed TiB₂–TiС ceramic composites

Considered in this paper is the effect of electron irradiation on the phasestructural state and micromechanical characteristics of reactively- and nonreactivelypressed TiB₂–TiС composite ceramic materials. It is shown that reactively-pressed specimens after irradiation demonstrate a growing tendency to phase formation, which considerably affects proceeding of relaxation processes in them. This special feature of reactively-pressed ceramics can improve radiation resistance of construction material

Potentiality of the composite fulleren based carbon films as the stripper foils for tandem accelerators

The problem of the radiation resistance of the carbon stripper foils is considered. The short review of the experimental data available in literature and original experimental results of the authors are presented. In the paper discussed is the possibility of composite fulleren based carbon films to be used for preparation of the stripper foils. Some technological methods for preparation of composite fulleren based carbon films are proposed. Raman scattering and atom force microscopy were used for investigation of the fulleren and composite films deposited by evaporation of the C60 fulleren powder
