A strong wiggler is likely to be required for the LCLS to reduce bunching that would cause beam instabilities due to coherent synchrotron radiation in the second linac bunch compressor. This wiggler will be located in a 3 m straight section immediately upstream from the bunch compressor at SLAC linac sector 24-7,where the e-beam will have an energy of 4.5 GeV. The peak field of the wiggler will have to be at least 5T, so a superconducting device is required. In this technical note,we describe a general design approach, and a specific proposal for this wiggler.
