HEAVY-CURRENT LINEAR ACCELERATOR OF IONS Russian patent published in 2002 - IPC

FIELD: accelerating equipment, in particular, devices in which acceleration of charged particles occurs due to their effective interaction with a radio-frequency electric field, applicable in creation of a barner-reactor for transmutation of long-lived radioactive nuclides contained in radioactive waste of nuclear power plants and nuclear submarines, as well as in microelectronics at formation of combined layers of ions. SUBSTANCE: accelerator has a cylindrical screen with end face flanges. Current-conducting rings are installed inside the screen perpendicularly to the axis, drift tubes with built-in focusing guadrupoles on permanent magnets are arranged on the rings uniformly in the circumference. The rings are interconnected by means of two diametrically positioned supports in such a way that the supports of the adjacent rings are mutually perpendicular. Each end face flange of the resonator has an annular bulge with half- tubes, four mutually perpendicular pins are installed on the outer cylindrical surface of the flange for azimuth movement, the pins have no electric contact with the inner surface of the screen, as well as with one another, movable contact devices connecting the outer surface of the ring and the inner surface of the screen, as well as the inner surface of one ring to the outer surface of the other concentrically positioned ring, are installed on each ring with the drift tubes. A unit of generation of RF-oscillations is positioned in the axis of the resonator, the unit has a high-voltage source of electrons, formation system and a channel for electron beam. The channel has ports in the end face flanges made in the axis of the resonator, electron drift tube with focusing magnets and gaps at the beginning and end of the resonator. Each end of the drift tube is fastened on the inner surface of the annular bulge by means of two or more holders. EFFECT: enhanced interelectrode capacitance and summary inductance of the oscillatory circuit, which in turn results in a considerable increase of the wavelength, and consequently, in the increase of the area of capture of particles and limit current of accelerated ions in each separate channel. 1 cl, 2 dwg
