摘要： A prefocusing lens section comprises a screen electrode (G2) and an additional electrode (G3). The main lens section comprises a focusing electrode (G5), an anode electrode (G6), and an intermediate electrode (GM) disposed between the focusing electrode and the anode electrode. The focusing electrode and the intermediate electrode comprise cylindrical electrodes (G5−3) and (GM−1) on their respective counter faces in at least one of them each. The intermediate electrode and the anode electrode comprise cylindrical electrodes (GM−3) and (G6−1) in their respective counter faces. A voltage having a level higher than a focusing voltage and lower than an anode voltage is impressed on the additional electrode and the intermediate electrode.

摘要： A pre-focus lens portion is composed of a second grid (G2) and a third grid (G3) and formed to have substantial rotational symmetry. A sub lens portion is composed of the third grid (G3) and a first segment (4-1). A main lens portion is composed of a fourth grid (G4) and a fifth grid (G5). The third grid (G3) is applied with a voltage that is higher than the focus voltage (Vf1) and lower than the anode voltage (Eb). An electron beam is so formed that the horizontal diameter is larger than the vertical diameter before incidence on the main lens portion.
