Abstract
A positive electrode drive unit enables a positive electrode to be repeatedly rotated about the center of the positive electrode to vary a distance between the positive electrode and an atom emission unit. A control unit receives input data which is set to obtain a desired atom density distribution by displacement of the positive electrode, and the control unit outputs a drive control signal for displacing the positive electrode to the positive electrode drive unit. The positive electrode drive unit is stopped during running by the control unit, or a drive speed of the positive electrode drive unit is changed by the control unit. Therefore, a residence time of each attitude is changed in the positive electrode to vary the atom density per unit time.
