PROBLEM TO BE SOLVED: To provide an induction voltage control device and control method thereof which is capable of accelerating arbitrary charged particles to an arbitrary energy level by synchronizing an induction voltage for acceleration with every magnetic field excitation pattern, even if an acceleration voltage is constant by induction accelerating cells for acceleration. SOLUTION: This induction voltage control system comprises a required variable delay-time pattern obtained based on a magnetic field excitation pattern, an equivalent acceleration voltage pattern, a digital signal processing unit 8d for controlling a variable delay time in response to the transit signal 7a of a bunch 3 sent from a bunch monitor 7; and a pattern generator 8b for converting a gate parent signal 8c to the gate signal pattern 8a of a switching power source 5b. As the control method of the system, pulse density is controlled per control unit of induction voltages for acceleration. COPYRIGHT: (C)2007,JPO&INPIT
