Abstract :
A description is given of the present performance of LEP. The major factors related to the limitations are discussed as ate the measures currently used to overcome them. The results from the “pretzel” scheme operation in 1994 are presented as well as a brief description of the new bunch train scheme. This scheme should ultimately allow the luminosity to be doubled by increasing the number of bunches per beam to sixteen (four trains of four bunches). The results and limitations from the energy calibration by resonant depolarization are summarized. A review is then given of the performance limitations, hardware requirements, and machine studies associated with operation of LEP at energies above the W± threshold. Finally the present plans for the LEP2 timescale are given
