Abstract :
Synchrotron radiation photons and off-energy electrons which contribute to backgrounds in the LEP experiments have been simulated. A multi-faceted background protection system has been designed and installed which permits the experiments to take data under very clean conditions. The backgrounds measured at LEP1 are in good agreement with calculations. Simulations and studies have led to a design of enhanced background protection for LEP2 where far more severe photon background is expected. Detector sensitivity to backgrounds and monitor systems are described.
