SEPTATE WAVEGUIDE WITH FOCUSING MAGNETIC FIELD Russian patent published in 2015 - IPC H05H3/04 

FIELD: physics.

SUBSTANCE: claimed waveguide consists of accelerating electrode. The latter is composed of cylindrical tank made of nonmagnetic material wherein excited is HF axially-symmetric electromagnetic travelling E-wave. Besides, it comprises accelerating gaps between irises with apertures at central lengthwise axis of accelerating waveguide. Said irises are made of magnetic flux conducting material with magnets arranged there between to develop the lengthwise axially-symmetric magnetic field. The latter deflects in accelerating gaps in accelerating aperture area towards the accelerating waveguide central lengthwise axis. Extra focusing by radial magnetic pressure originates in accelerating gaps along with the focusing of the beam by crosswise component of E-wave accelerating electric field central lengthwise axis and retention of the beam of charged particles from angular divergence of horizontal component of created magnetic field. Said field results from deflection of magnetic field power lines towards accelerating waveguide central lengthwise axis. This downs the loss of charged particles at their acceleration and facilitates the ion beam current at accelerator outlet. Invention allows efficient acceleration both high-intensity ion beams and high-charge-density high-intensity ion beams.

EFFECT: increased current of accelerated ion beam at accelerator outlet, reliable operation, ease of production, lower costs.
