Title: High Power Electron Gun for Metal Additive Manufacturing Based on Superconducting Technology

Abstract

E-beam additive manufacturing is a rapidly growingindustry. Electron guns capable of reaching higher energiesand higher average power can enable larger melt pools,higher production speed, and permit broader range ofmaterials for metal additive applications. Such electronguns require technologies beyond those normally achievedwith DC high voltage sources. As an example,superconducting radio frequency (SRF) technology is anoption to achieve higher energy and higher power withexcellent efficiency. However, current SRF technologyrequires complex cryogenic systems to safely handlecryogenics gases or liquids such as Helium. Suchcomplexity severely restricts their usage to R&D facilities.In this talk, we introduce and describe, for the first time, anovel technique based on SRF technology to build a highpower, high energy electron gun for advanced metaladditive manufacturing applications. Our design is based ona technique which eliminates liquid Helium entirely. Ourmethod dramatically reduces the complexity and thusallows building practical, efficient, and modern electronsources for additive manufacturing.
