    Abstract: An electron-beam generator comprises a cathode with a thermionic emitter, an anode and an electromagnetic system means; opposite said thermionic emitter there is disposed an additional electrode maintained at a negative potential relative to said anode; the electromagnetic system means establishes a magnetic field with the lines of force thereof curved through an angle close to or exceeding 90*; the cathode, anode, additional electrode and electromagnetic system means are disposed with respect to one another in such a manner as to act upon the electron beam in the direction of the curve of the magnetic field lines and to bend the electron beam in the plane of the magnetic field lines through an angle larger than said angle of curvature of the magnetic field lines by a value close to or exceeding 90*, with the result that in an acceleration area the electron beam travels across, and, upon completion of the acceleration phase, along the lines of force of the magnetic field. The electron-beam generator may be employed in electron-beam furnaces for vacuum heating and melting of metals, as well as in ultra-high frequency instruments and amplifiers wherein the electron beam interacts with the electromagnetic field.
