LASER ION SOURCE Russian patent published in 2003 - IPC

FIELD: acceleration engineering, ion implanting technologies and other industries using charged-particle sources. SUBSTANCE: laser ion source has target, laser, transit-time channel in the form of metal tube whose longitudinal central axis is aligned with original direction of hydrodynamic flow of plasma from target, and ion extraction system mounted on central longitudinal axis of transit-time channel; magnets are installed in transit-time channel so that they form in the latter multiple magnetic field inside the latter over entire length between target and ion extraction system; magnetic lines of force of this field are perpendicular to longitudinal axis of transit-time channel and its intensity approaches zero on central longitudinal axis and abruptly rises in vicinity of transit-time channel walls. EFFECT: enhanced efficiency of plasma holding in transit-time channel; reduced difference in speeds and angles of ion beam extracted from such source. 1 cl, 2 dwg
