摘要：

A new high-power electron accelerator for industrial applications has been developed in Novosibirsk. The main parameters of the accelerator are: operating frequency of 178 MHz, electron energy of 5 MeV, and average beam power of up to 300 kW. The accelerator consists of a chain of accelerating cavities connected by on-axis coupling cavities with coupling slots in the walls. A triode RF gun on the base of a grid-cathode unit placed on the wall of the first accelerating cavity is used for internal injection of electrons. The paper presents the results of modeling and optimization of the accelerating structure, internal injection, and beam dynamics. A modification of the electrostatic computer code SAM designed for simulation of beam dynamics in linear RF accelerators by the long-wave approximation method is described. (c) 2005 Elsevier B.V.
