Abstract
Components for use in vacuum electron devices are fabricated from highly oriented pyrolytic graphite (HOPG) and exhibit excellent thermal conductivity, low sputtering rates, and low ion erosion rates as compared to conventional components made from copper or molybdenum. HOPG can be reliably brazed by carefully controlling tolerances, calculating braze joint material volume, and applying appropriate compression during furnace operations. The resulting components exhibit superior thermal performance and enhanced resistance to ion erosion and pitting.
