【 摘 要 】

This is a more comprehensive report of the accelerator physics in the white paper 'PEP-X Light Source at SLAC'. A new light source called 'PEP-X' would reside in the 2.2-km PEP-II tunnel. It has a hybrid lattice where two of its six arcs contain DBA cells that provide a total of 30 straight sections for insertion device beam lines and the remaining arcs contain TME cells for an extremely low emittance. Using 90 meter damping wigglers the horizontal emittance at 4.5 GeV is further reduced to 0.1 nm-rad. Many collective effects including intra-beam scattering, Touschek lifetime, and fast ion instability are studied. We expect that PEP-X will produce photon beams having brightnesses near 10{sup 22} (ph/s/mm{sup 2}/mrad{sup 2}/0.1% BW) at 10 keV and 10{sup 21} at 35 keV.
