摘要

This invention provides a treatment device for lowering electron affinity, said treatment device being capable of performing an EA surface treatment on a photocathode material or an EA surface retreatment on a photocathode, and an electron-beam device provided with said treatment device. An activation chamber (20) used in a treatment device for lowering electron affinity by vaporizing a surface-treatment material (30) and using the vaporized surface-treatment material (30) to perform an electron-affinity lowering treatment on a photocathode material (52) or an electron-affinity lowering retreatment on a photocathode (52), said activation chamber (20) being characterized by containing holes through which electrons can pass.
