Dynamical Effects Due to Fringe Field of the Magnet in Circular Accelerators
Yunhai Cai, Yuri Nosochkov
The leading Lie generators, including the chromatic effects, due to hard-edge fringe field of single multipole and solenoid are derived from the vector potentials within a Hamilton…

Lattice and Compensation Schemes for the PEP-II Interaction Region
Y. Nosochkov, Y. Cai, M. H. R. Donald +4
The PEP-II interaction region is designed to accommodate asymmetric beam energies, head-on collisions, small bunch spacing and provide low beta* for high luminosity. Local correcti…

New Method of Dispersion Correction in the Pep-II Low Energy Ring
I. Reichel, Y. Cai
The sextupole magnets in the Low Energy Ring (LER) of PEP-II are grouped in pairs with a phase advance of 180 degrees. Displacing the magnets or moving the orbit to displace the be…
