The LEP Superconducting RF system reached its maximum configuration of 288 four-cell cavities powered by 36 klystrons in 1999. In 2000, this system, together with 56 cavities of the original copper RF system, routinely provided more than 3630 MV, allowing the beam energy to be raised up to 104.5 GeV. This not only required operating the cavities more than 15% above their design gradient, but has also demanded a very high operational reliability from the entire system. This paper will describe the operation of the LEP RF system during 2000, including new features, operational procedures and limitations.

The FCC-ee is a high-luminosity, high-precision e+e− circular collider, envisioned in a new 80100 km tunnel in the Geneva area. It is envisaged to operate the collider with centre of mass energies ranging from 90 GeV for Z production to 350 GeV at the tt threshold. With a constant power budget for synchrotron radiation, the FCC-ee RF system must meet the requirements for both the highest possible accelerating voltage and very high beam currents with the same machine, albeit possibly at different stages. Beam-induced higher order mode power will be a major issue for running at the Z pole, and will have a strong impact on the RF system design. Iterations are ongoing on RF scenarios and staging, choice of cavities and cryomodule layout, RF frequency and cryogenic temperature.
