Spontaneous coherent super-radiative emission in the terahertz frequency range from a short dense electron bunch is studied for various regimes. If the wave group velocity is close to the bunch velocity, this is a process of spontaneous radiation fol

Project of sub-THz/THz band FEL driven by linac "LIU" 5 - 20 MeV / 2 kA / 200 ns is under development in collaboration between BINP RAS (Novosibirsk) and IAP RAS (N.Novgorod). This project is aimed to achieve sub-GW power and a record pulse energy co

A natural problem arising in the case of realization of a electron maser operating in the terahertz frequency range is the use of oversized microwave system (with characteristic sized significantly exceeding the operating wavelength). In this situati

We study 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. Since the group velocity of the wave is close to the bunch velo

Novel schemes of a trapping regime in FELs were studied. Proof-of-principle experiments on realization of “non-resonant” trapping were performed at Ka-band. For short-wavelength FELs we describe two different ways of the use of regime of “multi

For relativistic oscillators, a new interaction regime is proposed based on the excitation of not a fixed transverse mode of the cavity, but a supermode formed by a fixed set of transverse modes. Such regime is implemented in a quasi-optical cavity b

The use of the “negative mass” regime can provide stabilization of longitudinal size of dense short photo-injector electron bunches at long distances as well as compression of the longer bunches. This allows one to increase significantly the powe
