Abstract

The LEP vacuum system extends over 26 km and consists of more than 6000 chambers, bellows, valves and special equipment. Adding the various pumps and gauges, a total of 13000 gaskets are required to mount all equipment. Hence, it is the largest vacuum system ever built for an accelerator. The procedures for all interventions, in particular leak detection, bake-out and commissioning, are of utmost importance for the global reliability of the vacuum system and will be detailed in this paper. As important for the global reliability are the power supplies and the remote control of the various equipment of the vacuum system. A careful initial design and preventive maintenance are the keys for it and will also be described
