Mr KOEPKE, Siegfried (DESY)


During operation of the accelerators at DESY, technical failures of individual subsystems, components or operational issues are repeatedly observed in addition of the failures of more complex technical systems.

Further improvement of the existing high availability must therefore be achieved by analyzing all types of failures and their causes, and also through a structured recording of the operational processes and their failure-free handling.

The in-house developed database application »qBase.« links the three most important sources of information from the accelerators PETRA-III, FLASH and EuXFEL together: expert knowledge from the operators electronic machine logbooks, status information and measured values from associated databases and at least detailed root causes from written failure event reports.

»qBase.« combines the information out of the mentioned sources and makes them accessible throughout DESY's Accelerator Division for advanced analytical investigations.
