Description
In the last number of years, maintenance of the Canadian Light Source (CLS) vacuum system has shifted from a reactive approach to a preventative maintenance approach. The catalyst of this shift is the aging facility and infrastructure. A comprehensive review and analysis of vacuum system components has given clear direction on preventative maintenance activities. Components that pose the greatest risk of failure are determined using the CLS enterprise risk management (ERM) framework. The ERM method often finds vacuum components to be in the high-risk category because of long lead times for parts and recovery time needed for vacuum conditioning. Risks to the vacuum system are strategically addressed using the risk quantification determined by the ERM analysis. Through the ERM framework and analysis, the status and health of the vacuum system is now better understood and necessary component spares and replacements are strategically determined. Design, fabrication, and procurement of strategic spares has increased the ability to respond quickly to failures, thereby reducing potential downtime. The reliability of the machine is increased as components posing the greatest risk to the vacuum system are replaced in planned shutdowns.
