Notes:
Undulator and wigglers are an essential basis for synchrotron radiation and free-electron laser systems. Wiggler and undulator design concepts for producing higher magnetic field strength with improved field quality are reviewed. Shim tuning methods have permitted magnetic field tolerances, including pole-to-pole field uniformity, trajectory straightness, and higher order moments, to be controlled to low levels as needed for various applications. A key figure of merit is the optical phase error, which determines the coherence of the light generated in the device. Coherence is a strict requirement for maintaining spectral intensity in synchrotron radiation sources with low emittance and maximizing gain in free-electron lasers. © 1996 American Institute of Physics.
