Abstract

1,013,622. Electron-beam tubes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. July 4, 1962 [July 7, 1961], No. 25659/62. Heading H1D. An electron gun for a electron-beam tube, e.g. parametric amplifiers, comprises a cathode 1 and at least two anodes or other electrodes 2-7 disposed in succession along the path of the beam wherein the cathode is disposed inside a magnetic screen formed by. the electrode 2 nearest the cathode, which electrode has an aperture of such size as to restrict the beam to a diameter of not more than half a millimetre, the cathode being shielded in operation from any external magnetic focusing field.
