The LEP Superconducting RF System

The basic components and the layout of the LEP RF system for the year 2000 are presented. The superconducting system consisted of 288 four-cell cavities operating at 352 MHz powered by 36 klystrons providing on average of 0.6 MW of RF power. This system was complemented by 56 cavities of the original copper RF system. A total accelerating voltage of 3630 MV could be provided routinely allowing operation up to 104 GeV. The installation schedule of the superconducting cavities is shown and comments are made about the evolution of the system over the years. The performance and the reliability of the final system are described.
