Optimizing the Injection Straight of PEP II Asymmetric B Factory at SLAC*

The power of the SLC linac, as a source for both elec-.trons &d po&rons, was demonstrated in the conceptual design report-(CDR) [l] (also see Table 1). A brief overview of the whole injection system is given in ReferenceJZ}. Figure 1 is a schematic of the system. One can divide the injection system into two main parts. The first is the extraction of e-e+ from the linac and their bypass lines leading to and matching into the existing NIT and SIT lines used in PEP The second is the injection straight, its optics and various components required for injection and matching into the main rings (HER, LER). The latter is the subject of this paper.
