The European Organization for Nuclear Research, CERN, stands at the forefront of fundamental physics, pushing the boundaries of human knowledge about the universe. This monumental endeavor, epitomized by the Large Hadron Collider (LHC), generates an unprecedented deluge of data, making the role of Artificial Intelligence (AI) not merely beneficial, but utterly indispensable. Recognizing AI’s transformative potential and its inherent complexities, CERN has developed a comprehensive AI strategy underpinned by a set of general principles designed to ensure its responsible and ethical use across all its activities. This guide explores the foundational principles that steer AI adoption at CERN, illuminating how this global scientific hub leverages cutting-edge technology while upholding its core values.

The Imperative for AI at CERN: Unleashing Scientific Potential

The scale of data generated by CERN’s experiments is staggering. The LHC, for instance, produces up to 40 million particle collisions per second, with each event generating approximately one megabyte of data. This translates to petabytes of raw information that must be filtered, processed, and analyzed to identify the rare signatures of new physics phenomena. Without advanced AI and machine learning (ML) techniques, extracting meaningful insights from this “data tsunami” would be an insurmountable task.

AI applications at CERN span a wide spectrum, from accelerating scientific discovery to optimizing operational efficiency and enhancing administrative processes.

• Scientific Research: AI is crucial for tasks such as event reconstruction, where raw detector signals are converted into identifiable particles, and anomaly detection, which helps physicists discover rare or unexpected events that could signal new physics beyond the Standard Model. ML algorithms are employed to analyze complex data from the Higgs boson and other particles, and to search for elusive entities like dark matter. Advanced simulations, vital for theoretical predictions, also heavily rely on AI to enhance accuracy and reduce computational costs.
• Accelerator Operations: Beyond data analysis, AI plays a critical role in maintaining and optimizing the world’s most powerful particle accelerator. This includes predictive maintenance of complex machinery, optimizing the quality and stability of high-energy proton beams, and enabling autonomous navigation and decision-making for robots operating in radiation environments.
• Productivity and Administration: AI also supports various administrative and productivity-enhancing tasks, such as automated translation, document drafting, coding assistance, and workflow automation, streamlining operations across the organization.

The integration of AI has become a strategic imperative, fundamentally reshaping research methodologies and operational paradigms at CERN.

Core Principles for Responsible AI at CERN

With AI becoming deeply embedded in its operations, CERN has established a set of technology-neutral general principles to guide the responsible and ethical use, development, and deployment of AI. These principles are designed to ensure that AI serves humanity’s quest for knowledge while adhering to the highest standards of integrity and accountability.

Transparency and Explainability

CERN emphasizes the need to document and clearly communicate when and how AI is used, as well as how AI contributes to specific tasks or decisions. This principle is vital for scientific validation, allowing researchers to understand the rationale behind AI-driven insights and fostering trust in its outputs.

Responsibility and Accountability

A cornerstone of CERN’s approach is that the use of AI, including its impact and outputs throughout its lifecycle, must never displace ultimate human responsibility and accountability. Humans remain in control, critically assessing and validating AI’s functioning and results.

Lawfulness and Conduct

All AI use at CERN must be lawful, compliant with CERN’s internal legal framework (such as the Code of Conduct), and respect third-party rights. This ensures that AI integration aligns with established organizational governance and ethical guidelines.

Fairness, Non-discrimination, and “Do No Harm”

CERN is committed to using AI in a way that promotes fairness and inclusiveness, actively preventing bias, discrimination, and any other form of harm. This is particularly relevant in data-intensive environments where subtle biases in training data could lead to skewed results.

Security and Safety

AI systems must be adequately protected against cybersecurity incidents, respecting confidentiality, integrity, and availability requirements. The safe use of AI is paramount to prevent negative outcomes and ensure the robustness of critical scientific and operational systems.

Sustainability

The environmental and social impact of AI use is also a consideration. CERN assesses its AI deployments with the goal of mitigating potential risks and enhancing its positive contributions to society and the environment.

Human Oversight

As previously mentioned, human oversight is a non-negotiable principle. AI’s functioning and outputs must be consistently and critically assessed and validated by a human, ensuring that technological advancements remain aligned with human judgment and ethical considerations.

Data Privacy

Given the extensive data processing at CERN, the use of AI must respect privacy and the protection of personal data, complying with CERN’s internal data protection framework, Operational Circular No. 11 (OC 11). This includes conducting Data Privacy Impact Assessments (DPIA) for significant technological changes involving personal data, ensuring strong access controls, limiting data categories, and monitoring AI outputs for potential biases.

Non-military Purposes

Crucially, any use of AI at CERN must be exclusively for non-military purposes. This principle underscores CERN’s dedication to peaceful scientific exploration and its role as a global beacon of international collaboration.

Architecting AI at Scale: Infrastructure and Collaboration

Implementing AI at the scale required by CERN’s ambitious scientific program necessitates robust infrastructure and a collaborative ecosystem. CERN leverages its formidable computing resources, including the Worldwide LHC Computing Grid (WLCG) and the CERN Data Centre, which collectively manage and distribute exabytes of data to a global community of thousands of physicists.

The organization actively utilizes and contributes to open-source technologies. Software development at CERN relies on a stack that includes Linux, Docker, Kubernetes, Java, and Python, ensuring broad applicability and knowledge sharing. For AI-specific tasks, popular frameworks like TensorFlow and PyTorch are widely adopted.

Collaboration is a key enabler of CERN’s AI strategy. Through initiatives like CERN openlab, a unique public-private partnership, CERN works with leading ICT companies and research organizations to accelerate the development of cutting-edge AI solutions. Strategic partnerships with EU programs, industry, and member states are vital for capacity building, securing funding, and expanding infrastructure to enable AI at scale. Furthermore, CERN is committed to attracting and developing top talent in AI, recognizing that human expertise is paramount for sustaining its scientific excellence.
