APPARATUS FOR TURNING ACHROMATIC BEAMS OF CHARGED PARTICLES

摘要

FIELD: physics. ^ SUBSTANCE: apparatus for turning achromatic beams of charged particles consists of two identical magnetic mirrors lying in the turning plane such that each of them turns the beam by half (compared to the required) angle. The design of the magnetic conductor and the windings of the mirrors enable decrease of the magnetic field (after increase thereof to the maximum at the edge of the mirror), which enables to compensate for the defocusing effect of the input region of the mirror. ^ EFFECT: invention enables to compensate for angular divergence of strongly non-monochromatic beams in a gap and obtain, after turning, beams with parameters close to those of the input beam. ^ 3 dwg
