Design and implementation of the CEE slow control system DevOps platform

Résumé fourni par la source

The CSR External-Target Experiment (CEE) facility, as China's first large-scale general-purpose nuclear physics experiment operating in the GeV energy region, relies on a slow control system built on the EPICS architecture to monitor hundreds of devices and process substantial data volumes. With increasing system complexity, manual operational efficiency decreases, making it difficult to maintain environmental consistency and ensure deployment reliability. To address these challenges, this study introduces a DevOps-based approach by integrating GitLab, Jenkins, Harbor, Kubernetes, and Ceph into an automated pipeline, leading to the design and implementation of the CEE Slow Control System (SCS) DevOps Platform. The main contributions include: (1) a continuous integration and delivery (CI/CD) pipeline customized for Experimental Physics and Industrial Control System (EPICS)-based control systems, (2) container image-based deployment and rollback strategies, and (3) operational security mechanisms covering log management, vulnerability scanning, and permission control. Test results demonstrate that the platform improves software delivery efficiency, ensures environmental consistency, and enhances operational reliability. This work offers a practical solution for developing and maintaining various control systems in large-scale scientific facilities.
