摘要

Abstract

A two stage echo-enabled harmonic generation (EEHG) scheme is proposed for a superconducting linac-driven FEL to produce coherent hard X-rays. Electron beams of quite different bunch lengths are separately used in each stage of EEHG and a monochromator is designed to purify the radiation from the first stage for seeding the second stage. Theoretical analysis and 3D simulations indicate that the proposed scheme can generate high repetition-rate coherent hard X-ray pulses directly from a conventional UV seed laser.
