| Outline of Final Research Achievements |
In accelerating a high intensity ion beam from a laser ion source, beam loss occurs due to beam divergence caused by the space charge effect. In this study, we have developed a beam acceleration device to extract the beam from the plasma and to control its trajectory. Based on the plasma simulation from the vicinity of the plasma generation area, the position to extract the beam in the plasma transporting solenoid magnetic field was determined, and an electrode system to control the trajectory of the acceleration beam by the electric field was designed. Experiments have demonstrated that by producing an electric field depending on the plasma transport magnetic field, the beam trajectory can be properly controlled and losses during the acceleration process can be suppressed.
