The Linac Coherent Light Source Undulator System

Abstract
Argonne National Laboratory is responsible for the delivery of the roughly 130-m long linac coherent light source (LCLS) undulator system. This system consists of 33 fixed-gap 3-cm period undulators, the associated vacuum system, diagnostics, controls and support hardware. Once completed the undulator system will be installed in a tunnel at the Stanford Linear Accelerator Center (SLAC). There, a roughly 14-GeV electron beam will be passed through the undulator system vacuum chamber and self-amplified spontaneous emission light with a nominal wavelength of 0.15 nm will be generated. The LCLS will be the first hard x-ray FEL laser designed solely for research and first light is scheduled for 2008. After a brief introduction of the LCLS project we will describe the specifics of the complete undulator system including the many design decisions and then provide a status of the various components.
