    摘要： A method corrects deflection defocusing in a cathode ray tube including an electron gun comprising a plurality of electrodes, an electron beam deflection device and a phosphor screen. This method includes placement of pole pieces of magnetic material in a deflection magnetic field produced by the electron beam deflection device and thereby locally modifies the deflection magnetic field in a path of an electron beam and corrects deflection defocusing of the electron beam corresponding to deflection of the electron beam in amount.

    摘要： A cathode ray tube which is equipped with an electron gun (K) having a construction capable of not only improving the focusing characteristics for the entire region of a screen (14) and for the total current range of an electron beam (10) without any supply of a dynamic focusing voltage to achieve a satisfactory resolution, but also reducing the Moire phenomena in a low current range. Also disclosed is a method of correcting the deflection aberration of the cathode tube. A deflection aberration according to the deflection of the electron beam (10) is corrected by establishing a fixed inhomogeneous electric field, which has its equipotential lines narrowed in interval the more for the longer distance from the axis of symmetry of an electric field.
