METHOD OF IONS ACCELERATION AND DEVICE FOR ITS REALIZATION Russian patent published in 2009 - IPC H01J27/24 H01S4/00 

FIELD: physics; nuclear.

SUBSTANCE: invention concerns nuclear and experimental physics and can be used in physics and equipment of direct ignition of targets of inertial thermonuclear synthesis. The method of acceleration of ions, is based on generation, allotment of ions and forming of a beam of ions from an ionised substance of a target with use of the concentrated laser beam. Isolation of ions and forming of a beam of ions is performed in a subsurface layer on a back surface of a target at controllable influence on a frontal surface of a target of relativistic intensity laser beam, thus a high-contrast (10⁵÷10¹⁰) relativistic intensity laser beam (10¹⁸÷10¹⁹ In g/sm²) of supershort duration (nearby 10^-2) is formed, which is directed with focusing on a frontal surface of the target for excitation of vortical electrons structure and forming of a vortical flow of relativistic electrons in a skin-layer of the frontal surface for generation of a quasi-stationary magnetic field and realisation of energetic induction and electromechanical influence on a layer of a back surface of the target with forming of plasma formation and toroidal plasma flow layer with isolation of ions and their acceleration to the receiver of ions in this layer. The device contains the pulse laser with the concentrator of energy and a target, the target is executed from an electroconductive copper substance with spattering on its back surface of a layer of an ionised substance, and for controllable effect on a target the pulsed laser with parametres of relativistic intensity (10¹⁶÷10²¹ W/cm²), of supershort duration (nearby 10^-2 s) is chosen, forming at functioning in a skin-layer on a frontal surface of the target the inductor for induction and electromechanical influence on a layer of a back surface of the target with forming of plasma formation in it with isolation of ions from plasma formation and their acceleration to the receiver of ions.

EFFECT: development of an effective way of ions acceleration.
