Terahertz generation of high-and low-frequency pulses from an ultrarelativistic electron
bunch, which move in a waveguide placed in an undulator, has been studied. If the length of …

To implement an efficient source of coherent radiation with negative mass longitudinal
stabilization, the methods of the formation and injection of a dense electron bunch onto a …

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 …

In this paper, we study spontaneous coherent undulator emission from a short dense
electron bunch. A special “negative-mass” undulator ensuring stabilization of the axial size …

We present the concept of creating sources of gigawatt-level powers in the subterahertz and
terahertz frequency ranges, which are based on excitation of high-Q cavities by high-current …

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 …

The use of electron–wave interaction systems consisting of several tapered sections is
considered as a method of efficiency enhancement of free-electron lasers (FELs) operating …

A description is given of the parameters and present state of the photoinjector electron
accelerator now being developed at the Institute of Applied Physics. The complex envisions …

It is shown that the process of a quasi-regular amplification of a long input wave pulse by a
short “slipping” electron bunch can be transformed into a different short-pulse process …

In this dissertation we present the development and characterization of a unique dynamic
environmental transmission electron microscope (DETEM) which combines ultrafast laser …
