    Abstract: The present invention relates to magnetic deflection devices for beams of charged particles. The system according to the invention comprises four deflecting elements arranged in pairs symmetrically with respect to a plane perpendicular to the plane containing the path of the beam. The distance between the faces of the deflecting elements is adjusted so that the energy conjugates of the two intermediate deflecting element coincide with the energy foci of the terminal deflecting elements. The device is thus achromatic.

    Abstract: The invention relates to a wave inverter, that is to say a device producing a transverse magnetic field alternately North-South and South-North polarised along the course of an electron beam and allowing, in a Free-Electron Laser, direct conversion of a portion of the energy of a beam of relativistic electrons into light energy. It relates to a wave inverter comprising a conductor (60) forming, along the path of the electron beam, windings or meanders inducing all or part of the transverse magnetic field. It consists, in order to increase the luminous efficiency, in providing on the said conductor (60) auxiliary current tapping outlets (P1,...Pj,...Pn) enabling the transverse magnetic field to be modulated as a function of the changing characteristics of the high-frequency electric field which increases during the arrival of an electron packet in the optical cavity of the Laser by virtue of the energy given up by them. … …

    Abstract: The invention relates to an undulator or wiggler, i.e., a device generating a sequence of transverse magnetic fields along the path of an electron beam and allowing, in a free-electron laser, the direct conversion of a portion of the energy of a beam of relativistic electrons into light energy. The undulator comprises a magnetizing circuit constituted by an electrical conductor which forms meanders along the path of the electron beam and in which a high excitation current flows, and a cooling system that evacuates the thermal energy dissipated by the excitation current in the meanders of the electrical conductor. Advantageously, the electrical conductor with meanders is made up of two superposed parts (210 and 211) forming meanders with a pi -shaped rectangular contour, and the cooling system is formed by an array of pipes with a flowing fluid.
