Title: Two-dimensional dusty plasma crystal as an electrostatic wiggler for free-electron laser

Abstract

The ability of a dusty plasma crystal to induce transverse motion to a relativistic electron, as a microstructure wiggler field in a free-electron laser (FEL), is presented. A dusty crystal wiggler with micrometer size can decrease FEL wavelength several orders of magnitudes. A relativistic electron dynamic through a two-dimensional monolayer hexagonal dusty crystal is analyzed. In addition to the usual transverse wiggling motion, second-harmonic amplitude is induced to the axial velocity. These conditions are compared with a magnetostatic planar wiggler, and it is shown that E{sub 0x}/V{sub parallel0} in dusty crystal has a role of B{sub w} in a magnetostatic wiggler. The strength of this proposed wiggler can be increased by decreasing d, decreasing d/{lambda}{sub D} ratio, or increasing q{sub d} in different experimental setups.

  • The system of the nonlinear nonstationary equations describing spatial-temporal dynamics of the amplitudes of an undulator radiation and a space charge wave of a relativistic electron beam in the resonator is obtained. The electrostatic longitudinal wiggler is considered. A bunch of the electron beam injects to the resonator, at the ends of which two mirrors are placed. After the interaction of electrons of bunch with radiation in the presence of wiggler and after amplifying electromagnetic pulse, a part of radiation is reflected back by semitransparent mirror. Then, it reaches to the initial of the system where the other mirror ismore » placed. Synchronously, when the pulse is reflecting, the other electron bunch enters to the resonator and interacts with the pulse. This operation has simulated until saturation of growth of the electromagnetic pulse. The dynamics of the problem is simulated by the method of macro particles. The dynamics of pulse amplification, motion of the electrons, and spectra of output radiation in each stage are simulated.« less
  • A new free-electron laser (FEL) scheme, using a periodic electrostatic field superposed on an electrostatic centrifugal system, is presented. By means of linear fluid theory, the Raman FEL dispersion equation is derived. We show that there is a new FEL instability near the electron transverse resonance besides the usual one near the beam resonance. The operating conditions, emission frequencies, and maximum growth rates of these two kinds of instabilities are obtained analytically. It is found that these results are in quite good agreement with numerical solutions of the dispersion equation.
  • The system of the nonlinear non-stationary equations describing spatial-temporal dynamics of the amplitudes of an ondulator radiation and a space-charge wave of a relativistic electron beam in the resonator is obtained. A free electron laser resonator with longitudinal electrostatic wiggler is considered. In the linear approximation, the threshold conditions of lasing for Raman and Compton regimes under excitation of forward and backward electromagnetic wave are achieved. In the various physical situations, the variation of the minimum length of the resonator with the amplitude of wiggler, density of electron beam, and with the reflection coefficients of resonator's mirrors is investigated.
  • The nonlinear electron orbit dynamics is presented for a combined electrostatic plasma wave wiggler and an axial guide magnetic field free electron laser near magnetoresonance. The perpendicular orbit equation is derived and simplified identical to the wave-driven nonlinear oscillator equation but with different expressions of parameters. The nonlinear effect induced by the inclusion of [beta][sup 2][sub [perpendicular]] [much lt] [beta][sup 2][sub [parallel]], where [gamma] = (1 [minus] [beta][sup 2][sub [perpendicular]] [minus] [beta][sup 2][sub [parallel]]) [minus] [sup 1/2]. The dependence of the maximum perpendicular wiggling velocity and the orbit excursion on the wiggler constant, the wiggler frequency, and the initial parametersmore » of motion is given analytically.« less
  • A three dimensional simulation software system developed to estimate a free electron laser (FEL) gain has been applied to FEL using a standard plane polarized wiggler and an alternately shifted magnet wiggler. It is seen for the latter wiggler that a large filling factor could be selected and each maximum gain corresponding to each orbit of electron beam concentrates at a certain frequency region of FEL radiation. It is, therefore, implied that a proper shift between the adjacent magnets in the wiggler produces the improvement of the FEL gain.
