The planned replacement of a functioning control system on the CERN 28 GeV accelerator

The design objectives for the new control system emphasise its power for operation and maintenance, its manageability and its future evolution. The availability of the accelerator complex is around 97%; this figure will be hard to improve, but the new control system must make it possible to maintain that standard. As far as future evolution of the control system is concerned, the trends are that more process equipment will be added, e.g. for the acceleration of antiprotons; and more complex tasks will be required (e.g. involving graphics interaction, optimisation, or automated sequences).
