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.
