  • Abstract
    High-perveance electron guns with a subfocusing electrode were designed analytically, produced, and tested. The experiments are carried out to evaluate the design method. Perveance of guns are 1.7 to 1.3 × 10-6A/V3/2, convergence angles being 30°. The results confirmed that it was possible to design electron guns of perveance up to 3.0 × 10-6A/V3/2.
