Cherenkov Radiation in Beam–Plasma Systems

Abstract

In this chapter, we will consider those processes of waves amplification that are conditioned by the elementary mechanism of the Cherenkov radiation emission. To distinguish this effect from others, we assume that the external magnetic field strength is very high. In this case, the cyclotron frequency of the electron rotation around the magnetic field lines essentially exceeds all characteristic frequencies emitted by the system in question. So, motion of the electrons can be treated as one-dimensional and directed along the magnetic field lines.
