Description
During Run 3 (2022 – 2026), the Large Hadron Collider (LHC) cryogenic system achieved an overall availability of 98.4%. Instrumentation and control equipment associated with the cryogenic plants was identified as one of the main contributors to the cryogenics system downtime. This presentation analyses the instrumentation and control failures that occurred during the run and examines how these and the corresponding repair activities are recorded in the operational database. Based on this analysis, improvements to the existing fault-tracking environment are proposed, with the aim of increasing system reliability through more systematic failure tracking and targeted preventive maintenance.
