implementation of a control system for a laboratory-scale 1 mev/25 kw electrostatic accelerator for irradiation experiments

This article presents the design and implementation of a control system for a 1 mev, 25 kw electrostatic accelerator, highlighting its architecture, instrumentation, and operational capabilities. the machine is designed for laboratory-scale irradiation experiments. a monolithic control system architecture was selected for its advantages in centralized data management, ease of maintenance, and simplified user access. the system integrates various subsystems, including a high-voltage rectifier, hartley-type oscillator, voltage multiplier, electron gun, acceleration section, cooling, and gas handling system. each of the subsystems are equipped with local and/or central interlocks for enhanced safety. the control software, developed using iec 61131-3 ladder language and the graphical programming language “g”, provides a user-friendly interface for real-time monitoring and adjustment of operational parameters. currently operational at 500 kv and 10 ma, the system demonstrates effective electron beam irradiation control, ensuring compliance with radiation safety regulations. future enhancements are planned to optimize performance and expand functionality for diverse experimental needs.
