Investigation of conical anode – disc cathode ion source

Autor: S. Abdel Samed, H. El-Khabeary, S.I. Radwan

Publikováno v: Canadian Journal of Physics. 96:194-201

An axial direct-current conical anode – disc cathode ion source has been designed, constructed, and operated. The electrical discharge and the output ion beam characteristics are measured using nitrogen gas. It is found that at the optimum dimensio
