Abstract

PURPOSE: To obtain the picture having high sharpness with high resolution, by increasing the performance, through the regulation of the ratio of the length of the specific electrode constituting the electron lens to the inner diameter size.
CONSTITUTION: Suceeding to the cathode 1, first grid 2, and second grid 3, the Ga electrode 9, Gb electrode 10, Gc electrode 11, Gd electrode 12 are placed as the major electron lens system. Further, the Ga electrode 9 and the Gb electrode 10 constitute the acceleration type bipotential lens, and the Gb electrode 10, Gc electrode 11, and Gd electrode 12 constitute unipotential lens. Moreover, intermediate potential E1 is applied to the Ga electrode 9 and Gc electrode 11 and high potential E2 is to the Gb electrode and Gd electrode 12. In the electron gun thus constituted, the ratio of the length of the Gb electrode 10 to the inner diameter D is taken as 0.2≤Lb/D<1.0, and further, the ratio of the length of the Gc electrode 11 to the inner diameter D is taken as 0.75≤Lc/D≤3.75.
