Abstract
A device is provided for injecting an electron beam propagating along an axis (x) in a cycloidal path under the action of a continuous electric field and a static magnetic field (B) perpendicular to the axis of propagation and to the electric field. The injection device comprises an electron gun placed in a weak magnetic field (B.sub.1) and means, placed in a magnetic field (B.sub.2) increasing progressively along the axis (x), for creating in this zone a continuous electric field having two components in the plane perpendicular to the magnetic field.
