Direct bonding for 60pcs oxygen-free copper (OFC) disk blanks with pulse electric current

Abstract

At GLC project, pair of liner accelerators will be built, facing each other as 33km total length and needs 18000pcs of 60cm X band accelerator structure. Now the manufacturing process of it is diffusion bonding with 72 hours, but we have to reduce process time. And so we tried direct bonding for 60 pcs OFC disk blanks with pulse current. Concerning this experiment, we developed new equipment which was an elastic electrode (CCE) for direct bonding. Then we got satisfied results on a basis experiment for accelerator structure manufacturing.
