摘要: The current status of development novel ion sources for materials science in Japan is reviewed. Several types microwave which permit a reactive gas discharge have been developed the production high intensity and low‐charge‐state beams. plasma cathode technique, as an electron source, provides conventional with long lifetime. Metal can deliver pure metal beam developed, extracting ions from temperature chamber large volume or porous tip surface. A new principle source by use cluster, consists hundreds to thousands atoms, has developed. High negative both light heavy ions, resulting in‐depth investigation mechanisms.
