Thousands of these devices, some in operation since 2007, directly impact LHC’s availability and reliability.This paper delves into comprehensive lifetime studies on these critical systems. The methodology involves estimating their remaining operational lifespan through detailed analyses of failure modes, assessing electronic component criticality, accelerated aging of electrolytic capacitors, inspections, and irradiation tests at both component and system levels. The study concludes by presenting essential findings, including the estimated remaining lifetime of each equipment. Additionally, the paper recommends future developments to enhance system robustness, offering valuable insights for maximizing the longevity of these critical devices. This research significantly contributes to ensuring the sustained reliability and performance of the LHC's magnet protection systems.
002912904 520__ $$aThe Quench Heater Discharge Power Supplies (HDS), Quench Discharge Local Protection Interface Module (DQLIM), Linear Redundant Power supplies (LPR), and Power Packs (LPUS) stand as critical systems, crucial for the protection of the Large Hadron Collider (LHC) superconducting magnets. This paper provides an in-depth exploration of comprehensive lifetime studies conducted on these systems. The initial segment outlines the methodology employed to estimate their remaining operational lifespan. This encompassing approach involves a detailed analysis of failure modes, evaluating the criticality of electronic components, accelerated ageing of electrolytic capacitors, irradiation tests conducted both at the component and system levels and an inspection plan. The study concludes by presenting essential findings, including the estimated remaining lifetime for critical components. This research serves as a significant contribution to ensuring the sustained reliability and performance of the magnet protection systems of the LHC.
