| Abstract | The ALICE experiment studies ultra relativistic heavy ion collisions at the Large Hadron Collider at CERN. Its Detector Control System (DCS) has been ensuring the experiment safety and stability of data collection since 2008. A small central team at CERN coordinated the developments with collaborating institutes and defined the operational principles and tools. Although the basic architecture of the system remains valid, it has had to adapt to the changes and evolution of its components. The introduction of new detectors into ALICE has required the redesign of several parts of the system, especially the front-end electronics control, which triggered new developments. Now, the DCS enters the domain of data acquisition, and the controls data is interleaved with the physics data stream, sharing the same optical links. The processing of conditions data has moved from batch collection at the end of data-taking to constant streaming. The growing complexity of the system has led to a big focus on the operator environment, with efforts to minimize the risk of human errors. This presentation describes the evolution of the ALICE control system over the past 15 years and highlights the significant improvements made to its architecture. We discuss how the challenges of integrating components developed in tens of institutes worldwide have been mastered in ALICE. |
