Description
A beam of relativistic charged particles, when entering the plasma, experiences beam-plasma instability. If the beam is long enough, longer than the plasma wavelength, it divides into a train of microbunches, namely, it self-modulates. This process is highly nonlinear, but under certain conditions becomes reproducible. The way the beam self-modulates depends on the parameters of the system, that is, the beam and the plasma. Properties of the microbunches formed in the plasma are strikingly different from those of the beams generated in conventional accelerators, and we created the analytical model to predict them. This study was supported by RSF grant No. 23-12-00028.
