FEL Gain Enhancement in an Optical Klystron

Anahit H. Shamamian, Hayk L. Gevorgyan, Lekdar A. Gevorgian

A system comprising two identical helical or planar undulators separated by a gap -- viz., an optical klystron (OK) -- is investigated. A formula for the frequency distribution of…

Line shape of soft photon radiation generated at zero angle in an undulator with a dispersive medium

Hayk L. Gevorgyan, Koryun L. Gevorgyan, Anahit H. Shamamian +1

The problem of undulator radiation from a bunch of charged particles, taking into account a medium polarization, is considered. In a dispersive medium, at a zero angle, in addition…

Partially Coherent X-Ray Oscilex Radiation from a FEL-Modulated Positron Bunch during Its Planar Channeling in a Crystalline Undulator

Hayk L. Gevorgyan, Lekdar A. Gevorgian

The radiation emitted at zero angle by a microbunched positron bunch undergoing planar channeling in a crystalline undulator (CU) is studied. The bunch energy is assumed to be far…

Dielectric permittivity of electron plasma with laser beat waves

Anahit H. Shamamian, Lekdar A. Gevorgian, Hayk L. Gevorgyan

Within the framework of the kinetic method, the process of interaction of a rarefied electron plasma with laser beat waves is investigated taking into account the initial spread in…

An RF Timer of Electrons and Photons with the Potential to reach Picosecond Precision

Amur Margaryan, Vanik Kakoyan, Simon Zhamkochyan +17

This paper describes a new radio frequency timer of keV energy electrons. It is based on a helical deflector, which performs circular or elliptical sweeps of keV electrons, by mean…
