摘要：

The upgrade of the Large Electron Positron collider (LEP) with superconducting cavities is nearing a successful completion. There are presently 240 superconducting cavities installed which, together with the original copper RF system, provide up to 2.6 GV per turn. The majority of the superconducting cavities are of niobium sputtered on copper and run at an operating gradient of 6 MV/m. In 1997, LEP has operated routinely at an energy of 91.5 GeV per beam and with a total current of over 5 mA. The operation of the RF system has been very satisfactory, with only a few cavities limited in field. This paper will concentrate on describing the operation of this system during 1997, including new features, operational procedures and present limitations. Future plans, notably the work towards improving performance and the installation of the remaining cavities, will also be covered.
