Abstract

PURPOSE:To compensate the amplitude of the scanned picture drawn by electron beams at the center and at the both external sides of an in-line type electron gun, by providing a new magnetic field control element to its deflection magnetic field at the electron beam passing area reached by the leakage magnetic field at the tail end of a deflection yoke.
