This book comprises the abstracts of the reports (presentations) for the oral and poster sessions of International Congress on Energy Fluxes and Radiation Effects (EFRE-2014). The Congress combines three International Conferences held in Tomsk: Symposium on High Current Electronics, Conference on Modification of Materials with Particle Beams and Plasma Flows, and Conference on Radiation Physics and Chemistry of Condensed Matter. The program of the Congress covers a wide range of technical areas and modern aspects of pulsed power technology, ion and electron beams, high-power microwaves, sources of plasma and particle beams, modification of material properties, pulsed power applications in chemistry, biology and medicine, physical and chemical non-linear processes in inorganic dielectrics under the action of particle and photon beams, and physical principles of radiation-related technologies.
