文摘

SLAC is developing a long-range plan to transfer the evolving scientific programs at SSRL from the SPEAR3 light source to a much higher performing photon source. One of the possibilities is a new PEP-X 4.5GeV storage ring that would be housed in the 2.2 km PEP-II tunnel (Hettel et al., 2008 [1]; Hettel et al., to be published [2]). The PEP-X is designed to produce photon beams having brightness near 10²² (ph/s/mm²/mrad²/0.1 % BW) at 10 keV with 3.5 m undulators at beam current of 1.5 A. This report presents an overview of the PEP-X baseline lattice design and describes the lattice optimization procedures in order to maximize the beam dynamic aperture (Wang et al., 2010 [3]). The complete report of PEP-X baseline design is published in SLAC report (Bane et al., 2010 [4]).
