Development of scanning magnet power-supply used in industrial radiation accelerator

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 th
