Abstract

A method of manufacturing a Radio Frequency (RF) coil for a multi-driven RF based negative ion source includes manufacturing a first coil and a second coil using tubes of stainless steel as a substrate material, coating the first coil and the second coil separately; and joining the first coil and the second coil by orbital TIG welding after coating the first coil and the second coil to provide the RF coil for the multi-driven RF based negative ion source.
