Abstract

AN IN-LINE TYPE ELECTRON GUN ASSEMBLY COMPRISES FIRST, SECOND, THIRD AN FOURTH GRID ELECTRODES.THE FOURTH GRID ELECTRODE (30) IS FORMED AS IN A TROUGH OR CUP SHAPE. A MAIN MAGNETIC FOCUS LENS IS FORMED BY AXIALLY ALIGNED APERTURES IN THE THIRD GRID ELECTRODES (28) AND FOURTH GRID ELECTRODES (30). AN AUXIALIARY ELECTRODE IS PROVIDED BETWEEN THE FOURTH GRID ELECTRODE AND A SHIELD CUP OF THE CRT. THE AUXIALIARY ELECTRODE (32) COMPRISES THREE GENERALLY TUBULAR, REARWARDLY-FACING AUXILIARY APERTURES JOINED TO A FLAT PLATE (32B). EACH AUXILIARY APERTURE INCLUDES TWO OPPOSED SIDE NOTCHES (32A). EACH NOTCH (32A) PREFERABLY HAS THE SAME GENERALLY RECTANGULAR SHAPE AND IS FORMED IN THE SAME AS THE DIRECTION OF BEAM ALIGNMENT. EACH NOTCH (32A) IS COUPLED TO AN UPSTANDING FORWARD-FACING LIP AROUND THE INSIDE EDGE OF THE APERATURES OF THE FOURTH GRID ELECTRODE (36). (FIG. 3)
