【Abstract】 Continuous triangle waveform as the magnetic field current of scanning magnet can give good uniformity degree of radiation in industrial radiation accelerator.This paper introduced the design of a scanning magnet power-supply used in a 10 MeV industrial radiation accelerator.The scanning magnet power-supply can produce continuous triangle waveform current.The frequency can be adjusted by step length of 1 Hz ranged from 20 Hz to 50 Hz,and the peak-to-peak current is 20 A.The principle of triangle waveform modulator,linear degree of triangle waveform,control system based on single-chip and it’s anti-jamming measure in industrial circumstance are presented.Both theoretical analysis and result of application show that linear degree of scanning and uniformity degree radiation of this design is better.更多还原
