Features of the formation of electron bunches upon the development of generation in multiwave Čerenkov devices

Аннотация

The dynamics of electron bunch formation are analyzed using data obtained by means of numerical simulation. It is shown that upon the development of microwave generation, electron bunches start to form in a relativistic flow in the first section of the electrodynamic structure. At the entrance to the second section, a complex structure of electron distribution over a longitudinal pulse is observed inside the bunch in the stationary mode of generation. It is concluded that the duration of a microwave radiation pulse can be increased by optimizing the length of the first section of the generator.
