Abstract
An ion source having a sintered metal head for ionizing various substances is disclosed. This ion source comprises a container made of a material which has a higher fusing point than that of the substance which is to be ionized, and a tip formed of a molded sintered metal of a higher fusing point than that of the substance which is to be ionized. The head is formed into a nearly conical shape and has a porosity capable of allowing the substance which is to be ionized to infiltrate therethrough in the molten state and the tip of the head is positioned at the opening of one end of the container for the ionizable material and arranged in such a manner that it protrudes beyond the end of the container.
