Undulator performance on PEP storage ring with different optics
Various magnetic optics have been considered for PEP storage ring which can be used depending on the operational circumstances. The storage ring for example is operated around 14.5 GeV when high energy investigations are carried out in which the positron and electron beams collide, the colliding-beam optics (CBO) mode. The low-emittance optics (LEO) has been tested at 8 GeV which is very useful for numerous synchrotron radiation studies. In addition, a new lattice with damping wigglers has been proposed which can provide very low emittance. This is referred to as very low emittance optics (VLEO). These lattices also provide straight sections with different lengths varying from 6 m in the symmetry straight, to 14 or 117 meters in the interactions regions which in principle would permit installation of very long undulator insertion devices for special applications. The ability to profitably utilize the radiation from these undulators proposed for PEP is determined by their performance in the different operating modes and by whether the design tolerance required for acceptable operation of the device can be met with available technology. The purpose of this paper is to provide spectral characteristics for some typical devices calculated using a Monte-Carlo algorithm in which the Lienard-Wiechert potential is integrated over the trajectory of the charged particle along the undulator length.
