The advanced techniques for an AVF cyclotron were developed to realize swift and frequent beam switching of the ion species and energy of an ion beam, and to provide highly-stable high-quality beam for special beam formation, such as a microbeam and a single-pulse beam. The high stability of the magnetic field was obtained by controlling the temperature of the magnet iron, and has enabled the fast and reliable beam switching. Based on the highly stabilized magnetic field, the sophisticated techniques for measurement and control of beam-phase and that of reduction of beam phase width by phase bunching in the central region of the AVF cyclotron were developed. Development of the advanced acceleration techniques have realized regular use of the special beams for the research in the fields of biotechnology and materials science.
