Three years of operational experience with the LEP RF system

The LEP copper RF system is characterised by the use of storage cavities coupled to the accelerating cavities, the number of such assemblies installed in the accelerator and the total RF power available. The physical distance between the various elements that makes up the total RF system is also specific to LEP. The RF system has now been running for more than three years under operational conditions in LEP. We report on the global operational experience during this period and on the performance of the various elements making up the LEP RF system
