Title :
The LEP energy upgrade project
Author_Institution :
CERN, Lab., Geneva, Switzerland
Abstract :
Beams approaching 90 GeV are planned for LEP (Large Electron-Positron colliding beam accelerator) by the year 1994. To this end, a total of at least 192 superconducting cavities will be installed in LEP until 1994, partly near the present copper RF accelerating cavities and partly at two new locations. The LEP energy upgrade requires modifications of the collider layout, a complete reinstallation of the magnet power converters powerful cryogenic plants, and a general upgrade of the LEP infrastructure, which will have to distribute and cool about twice the present energy requirements. The various activities and their planned milestones are presented, with the aim of providing a general view of the project goals and of the present status.<>
