A new electron gun has been developed for large perfectly flat color monitor tubes by redesigning the DQ-DAF(double quadrupole-dynamic astigmatism and focus)electron gun. The new electron gun features a rectangular G1-aperture, a newly developed main lens with a large effective diameter, and a new lens system using a static quadrupole lens immediately behind the main lens. The effect of the static quadrupole lens was investigated by analyzing the spot. It was found to reduce lens magnification in the horizontal direction and enlarged it in the vertical direction. As a result, spot distortion at the screen periphery was clearly reduced due to the smaller horizontal spot size. The dynamic voltage was also reduced.
