Single Wavelength Standard Wiggler for PEP

A 1¿ planar wiggler has been designed that will be used for the initial operation of the 4-18 GeV storage ring PEP. Three of these wigglers will be installed symmetrically around the ring at 120° intervals in three of six available 5 m straight sections with the purpose of providing: (1) beam size control to obtain better luminosities below 15 GeV, and (2) decreased damping times to obtain better injection rates at lower energies. Design goals are discussed and a description of the final system including cost estimates is given. Expected results and usage in PEP are discussed. Some possibilities for production of synchrotron radiation and beam monitoring with shorter wavelength, multipleperiod wigglers at PEP energies are also discussed. Comparison to a wiggler now operating in SPEAR is given.
