Abstract

The slow extraction from the CERN PS to the East Area was completely rebuilt in March 1992. The new layout benefits from several improvements. The losses on the magnetic septa are suppressed by means of a novel concept applied to the third-integer resonance optics. The vacuum has been improved (in view of future lead ion acceleration) by means of a reduction in the number of septa and a change in their technology. Synchrotron radiation damage during lepton cycles is avoided by installing the septa on the inner side of the machine aperture. Maintenance is simplified, servicing eased and personnel radiation doses reduced by the use of modular plug-in units. The beam dynamics, the layout, the main characteristics of the hardware and the resultant performance are presented
