Tolerance Study for the Echo-Enabled Harmonic Generation Free Electron Laser

Conference ·
OSTI ID:953499
The echo-enabled harmonic generation free electron laser (EEHG FEL) holds great promise in generation of coherent soft x-ray directly from a UV seed laser within one stage. The density modulation in the harmonic generation process is affected by the smearing effect caused by the fluctuations of energy and current along the beam, as well as the field error of the dispersive elements. In this paper we study the tolerance of the EEHG FEL on beam quality and field quality. The diffusion effect from incoherent synchrotron radiation (ISR) in the dispersion sections and the second modulator are also studied.
