A cathode electrode is disposed along an axis. A repeller has a repeller shaft and a ceramic target member separated by a gap. The repeller shaft is not in electrical or mechanical contact with the target member, and the repeller shaft is configured to indirectly heat the target member. The target member, can be a cylinder encircling the repeller shaft, where the gap separates the cylinder from the repeller shaft. A top cap can enclose the cylinder can be separated from a top repeller surface of the repeller shaft by the gap. A target hole can be in the top cap. The target member can be supported by a bottom liner of the arc chamber or a support member mechanically and electrically coupled to the repeller shaft."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ion source repeller","description":"An ion source has an arc chamber having one or more arc chamber walls defining and interior region of the arc chamber.
