摘要：

A metal atomic beam was produced by electron beam heating with high efficiency using a hearth liner and a porous rod for cerium and gadolinium. While the top surface of the porous rod was heated by an electron beam, the molten evaporation material surrounding the rod was transferred to the top surface by capillarity; then the atomic beam was produced from the top surface. For every evaporation material, an extremely high atomic beam flux with high stability was obtained even at low input power, without contamination by tungsten atoms from the porous material.
