LEP status the machine and the experiments

LEP is now very close to completion. The magnets, vacuum system, RF, diagnostics, infrastructure, etc. are in place and undergoing final testing. Much the same can be said about the four LEP detectors. Detailed plans for the commissioning of LEP are laid. The present report provides some information on what has been hapenning at LEP in recent months, and then briefly outlines the programme evolving in the immediate and longer term future. LEP is located within a circular tunnel 27 km in circumference which staddles the border between France and Switzerland. It lies at depths ranging between 50 and 170 m below ground level and is constructed on a slope of 1.4 % to maximize the amount of good rock in which it is built and to minimize its depth under the Jura mountains. The LEP machine is described in the present report focusing on the injection into LEP and the LEP main ring. Features of the four large detectors for LEP, called ALEPH, DELPHI, L3 and Opal, are outlined. The LEP programme is also outlined briefly. When LEP first comes into operation, the amount of installed FR power will be sufficient to accelerate the electrons and positrons up to energies of approximately 55 GeV per beam. (N.K.)
