High capture rate has been achieved by using an electron gun with high-frequency beam current control, entrance PCS resonators focusing the beam, and in-built into the PCS magnetic periodic focusing system of the solenoidal type based on permanent magnets (MPFS). This study investigates beam dynamics in the developed gun and PCS. The electron gun forms a cylindrical weakly-converging beam in the first resonator of the PCS as a sequence of short pulses with the accelerating frequency, the first and following resonators of the PCS focus, group and accelerate the beam and MPFS focuses and transports electrons to the PCS exit.
