Abstract:
Background In high-current linear induction accelerator (LIA) systems, power supplies constitute an indispensable and numerous category of equipment, providing energy for the beam transport and the magnetic and electric fields required for particle acceleration.. However, no universal power control prototype system suitable for high-current LIAs currently exists.
Purpose To enhance the development efficiency of high-current LIA power supply control systems, this paper designs a prototype power control system based on the EPICS (Experimental Physics and Industrial Control System) architecture.
Methods This system employs command distribution and trigger execution to concurrently manage the operational states of hundreds of power supplies. It utilizes “macros” to develop IOC (Input/Output Controller) programs and leverages Phoebus and embedded Python scripts to create the OPI (Operator Interface), delivering a user interface characterized by simplified operation and diverse status display capabilities.
Results This control system has operated stably for over a year within the high-current LIA correction field excitation power supply control system, passing long-term online operation evaluations.
Conclusions The designed power supply control prototype system is scalable for controlling power supply clusters for beam transport main magnetic field, correction magnetic field and acceleration electric field in both single-pulse and multi-pulse configurations of dual high-current LIAs.
