Abstract :
A magnetic beam-separation scheme for an asymmetric-energy B-factory based on the SLAC (Stanford Linear Accelerator Center) electron-positron collider PEP (Positron Electron Project) is described. It has the following properties: the beams collide head-on and are separated magnetically with sufficient clearance at the parasitic crossing points and at the septum, the magnets have large beam-stray-clear apertures, synchrotron radiation produces low detector backgrounds and acceptable heat loads, and the peak beta -function values and contributions to the chromaticities in the IR quadrupoles are moderate.<>
