Abstract

PURPOSE: To obtain excellent blooming and halo performance by setting the performance coefficient of an electron gun with composite type principal electron lenses to the ranges 3W4.
CONSTITUTION: The relative relationship G3L G5L/(G4L+g1+g2), i.e. the performance coefficient of a composite type principal electron lens system for each value of the electrode length G3L of the third grid 4 which forms the composite type principal lens system, electrode length G4L of the fourth grid 5, electrode length G5L of the fifth grid 6, the interval g1 between the third grid 4 and the fourth grid 5, and the interval g2 of the fourth grid 5 and the fifth grid 6 is set to the ranges 3W4.
