A Capacitor Model of the Helical Deflector: Revisiting Shamaev's Proposal and the Textbook Model
Hayk Lekdar Gevorgyan
An RF helical deflector is a type of electron and ion optics device that applies a time-dependent rotating transverse electric or magnetic field by means of time-dependent RF volta…
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…
Coherent radiation of microbunched beam in stack of two plates
Hayk Gevorgyan, Lekdar Gevorgyan, Karo Ispiryan
The present article is devoted to the radiation from an electron bunch with modulated density passes through the stack consisting of two plates with different thicknesses and elect…
Positron Bunch Radiation in the System of Tightly Packed Nanotubes
Hayk L. Gevorgyan, Koryun L. Gevorgyan, Lekdar A. Gevorgian
Radiation emitted by a bunch of positrons channeled in nanotubes at zero emission angle is studied taking into account medium polarization. The formation of radiation is characteri…
