Outline of Final Research Achievements	We have developed a method to control the current density of an extracted beam from a plasma produced in a laser ion source by introducing solenoid electromagnets between the laser ion source and the beam extraction electrode. Two solenoid magnets are designed and build based on ion trajectory calculation. The experimental study demonstrated that the ion current density was increased up to about 2.4 times by adjusting the solenoidal magnetic field.
