Compact Gamma-Beam Source for Nuclear Security Technologies

Abstract

A compact gamma-beam source dedicated to the development of the nuclear security technologies by use of the nuclear resonance fluorescence is described. Besides, such source is a very promising tool for novel technologies of the express cargoes inspection to prevent nuclear terrorism. Gamma-beam with the quanta energies from 0.3 MeV to 7.2 MeV is generated in the Compton scattering of the "green" laser photons on the electron beam with energies from 90 MeV to 430 MeV. The characteristic property of the proposed gammabeam source is a narrow spectrum (less than 1%) at high average gamma-yield (of 10 13 γ/s) due to special operation mode.
