Abstract

PURPOSE: To improve the building precision of electron guns made in one, to improve the aberration of an electron lens by making several beams symmetrical on the tube axis and adjacent one another, and to improve focus characteristics by forming electron lens in one for a long lens diameter.
CONSTITUTION: A hot electron flying out from one cathod 13 reaches beam aperture 9 with several apertures after the beam amount is limited by grid potentials of the 1st grid 12 and 2nd grid 10 with several apertures and slight focusing action is given. Here, the diameters of respective electron beams are limited. Then, alignment coil 11 adjusts individual positions of electron beams and the relative position among beams at the same time. Apertures of grinds and beam apertures are made symmetric on the tube axis and adjacent. Consequently, the aberration of the electron lens is improved.
