Beam dynamics study of a 100 MeV RF electron linac

Abstract

Linac based pulsed electron beams of energy 30-100 MeV and several kilowatts are used to generate neutrons by photo-nuclear and photo-fission reaction mechanisms for neutron beam irradiation application areas like material science studies and measurement of neutron cross-section, scattering cross-section, capture cross section, fission cross section. Considerable high beam power obviously demands minimizing the high-energy particles loss during their acceleration and transport. This paper presents the simulation results for a 100 MeV and 100 kW linac using the beam dynamics codes ASTRA and ELEGANT for delivery of a high quality beam.
