The control system’s functionality and performance are vital for the accelerator’s reliability, stability, and efficiency. The PW laser accelerator control system has a three-layer distributed architecture, including device control, front-end (input/output) control and central control (data management, and human-machine interface) layers. The software platform primarily uses EPICS, supplemented by PLC, Python, and Java, while the hardware platform comprises industrial control computers, servers, and private cloud configurations. The control system incorporates various subsystems that manage the laser, target field, beamline, safety interlocks, conditions, synchronization, and functionalities related to data storage, display, and more. This paper presents a control system implementation suitable for laser accelerators, providing valuable insights for future laser accelerator control system development.
