Calculation of electron beam dynamics of accelerator LUE-200

Calculations are performed for the focusing and transport system of an electron beam of the LUE-200 accelerator - the driver of a pulse source of resonant neutrons (IREN). The calculations of the beam dynamics in the travelling wave accelerator were carried out with the help of the PARMELA code for a designed configuration: elements of the accelerating system, the system of magnetic focusing of the accelerator from an electron source up to the end of the accelerating structure, the channel of beam transport from an output of the accelerating structure up to a target. Modelling of modes of acceleration and transportation is performed for various parameters of the focusing magnetic field in the accelerator and the channel, for various currents of the beam and various initial distributions of electrons
