Reliability run and data analysis of the accelerated aging of present and future electrolytic capacitors installed in the protection systems of superconducting magnets of the Large Hadron Collider at CERN

Abstract

This study evaluates the lifetime and aging process of the aluminium electrolytic capacitors to be used in the new protection systems of the High Luminosity LHC superconducting magnets. The accelerated testing and analysis of several groups of capacitors aged for more than one year provided insights into their expected lifespan and aging process. The results obtained have practical implications for maintenance and replacement schedules, as well as for selection and acceptance of capacitors for new Heater Discharge Power Supplies (HDS) equipment. The knowledge gained from this study ensures the safety and reliability of the LHC and its electronic components.
