Outline of Final Research Achievements

A PIG ion source was developed to be mounted in a compact MeV ion microbeam system. The main performance of the ion source was to generate ion beams with low energy, high brightness, and small energy spread in addition to small electric power consumption and long term maintenance. Especially, the brightness is important for the performance. A prototype of PIG ion source with electric magnets was developed to investigate mainly the relationship between the brightness and the strength of magnetic field. Then a PIG ion source with permanent magnets, which generates the strength of magnetic field to produce the brightness obtained from the investigation, was developed for further reducing the electric power consumption. The preliminary studies that generated hydrogen ion beams indicated that the aimed performance was almost satisfied by the PIG ion source with permanent magnets.
