SPS and LEP Controls, Status and Evolution Towards the LHC Era

LEP was the first CERN accelerator to be built with a control system using commercial, UNIX based technology. Operational experience has confirmed the strategies of the original design. However, to maintain this system, components have to be renewed and to meet the increasing user demands the system requires continuous investment.

This investment has ensured that the control system is still based on a modern controls infrastructure and the recent extension to the SPS machine and its Experimental Areas has been achieved without any specific developments of the basic infrastructure.

We present a status report of the Control System today and describe the current work to maintain and prepare for future application in the LHC era.
