The FEL and IFEL design study for the proposed NTHU photon-electron dynamics laboratory

A photon-electron dynamics laboratory is being proposed at National Tsinghu a University, Taiwan. The mission of the proposed laboratory is to conduct advanced research on free-electron laser, inverse free-electron laser, and laser-driven particle acceleration. We discuss in this paper the design stu dy of the Stanford high efficiency FEL and the reconfigured Stanford/TRW wi ggler in the proposed laboratory. The Stanford high efficiency FEL is to de monstrate a 19% beam-to-laser efficiency. The reconfigured, 1-m Stanford/TR W wiggler may serve as an inverse FEL that provides 1.5-mu m bunched electr ons for various kinds of laser-driven acceleration experiments.
