Short dense electron bunches produced by modern photoinjectors are attractive from the viewpoint of the realization of powerful and effective sources of subterahertz radiation based on the spontaneous coherent mechanism of emission. This type of emis

We discuss the concept of creating sources operated in the sub-terahertz/terahertz frequency range with a multi-megawatt power level and based on the coherent spontaneous emission of intense electron bunches. The possibility of forming such bunches i

We describe the concept of an amplifier based on a principally nonlinear effect of reflection of an electron bunch from a short powerful wave pulse. This is an effective mechanism of energy extraction by the wave from particles which does not require

Dense short electron bunches produced by state-of-the-art photoinjector-based accelerators are used to create sources of powerful electromagnetic pulses of terahertz frequency range based on spontaneous coherent emission by these bunches. However, th

Short dense electron bunches generated by today’s photoinjectors [1–5] are advantageous for creating powerful sources of spontaneous coherent radiation in the terahertz frequency range. The regime of spontaneous radiation is achieved when the bun

Two experimental gyrotron test benches in the terahertz frequency range with large-orbit electron beams operating at high harmonics of the cyclotron frequency are created at the Russian Academy of Sciences’ Institute of Applied Physics. An overview

A natural problem arising in the case of realization of a THz electron maser with a high-current relativistic electron beam is the use of an oversized cavity when it is difficult to provide selective excitation of a definite transverse mode. Our idea

There are results for the spontaneous coherent super-radiative undulator emission in the terahertz frequency range from a short (as compared to the wavelength of the radiated wave) dense electron bunch. If the group velocity of the wave is close to t
