Heavy Ion Research Facility in Lanzhou-Cooler Storage Ring control system

HIRFL-CSR (Heavy Ion Research Facility in Lanzhou-Cooler Storage Ring) control system has been working normally for nuclear physics experiment and tumor therapy experiment in recent years. HIRFL-CSR control system is a large distributed control system designed for completing HIRFL-CSR. HIRFL-CSR control system has three tiers: business tier, front-end control tier and device control tier. Business tier mainly includes control management program, central database and synchronous timing system; front-end control tier mainly includes front-end server and front-end controller; device control tier mainly includes MCU multifunction controller and controlled device. The central database stores all accelerator control data and provides data to support accelerator changes beam energy. HIRFL-CSR control system can basically meet nuclear physics experiment and tumor therapy experiment requirements, which is based on long-running situation.
