Abstract
A solid dielectric material is installed between the second focus electrode and third focus electrode in a one-pin dynamic electron gun assembly in order to increase capacitance between the two electrodes. The increased capacitance between the two electrodes reduces the voltage Vg between the two electrodes and increases the effective voltage Vd (eff) between the third focus electrode and the fourth focus electrode since Vd=Vg+Vd (eff).
