Rejuvenation of the CPS control system: the first slice

The consolidation of the CERN accelerator control systems is expected to be completed in 1995. As a first slice for the CPS complex, the LEP (Large Electron-Positron colliding beam accelerator) Preinjector (LPI) was chosen for its coherent wholeness as a particle source and as a system with a reasonable amount of equipment to control. This machine is large enough to be a good validation testbed for the control architecture, and modern enough to reduce the software porting problem. A general overview of this rejuvenation plan and a detailed analysis of the first slice are presented, including the estimation of the manpower, together with the selected options. >
