METHOD AND DEVICE FOR LASER ELECTRON ACCELERATION Russian patent published in 2001 - IPC

FIELD: acceleration of charged particles, well as laser physics, applicable in development of charged- particle accelerators of an essentially new type. SUBSTANCE: at accomplishment of the method for laser acceleration the electron beam is injected perpendicularly to the axis of the laser beam of arbitrary intensity possessing a combination polarization of the electromagnetic field, injection is effected on the side of circular polarization of the field in such a way that replacement of the circular polarization with the linear one would occur during passage of the accelerated electron through the central part of the laser beam. The device for realization of the given method consists of a laser, driver of the accelerating field and an electron ejector. The dual-frequency laser is made with a similar intensity of linearly polarized beams at frequencies ω₁ and ω₂, polarizations of the beams are orthogonal relative to one another, and the difference of frequencies (ω₁-ω₂) ≈ V_o/r_o, where V_o - average electron speed, r_o - beam radius, and the driver is made in the form of a mixer combining both radiations in a single beam, and a laser amplifier of this beam. EFFECT: enhanced efficiency of laser electron accelerators without essential space modulation of electron beam. 2 cl, 2 dwg
