Considerations on implementing EEHG with a strong linear chirp
(2019) 39th International Free-Electron Laser Conference, FEL 2019 In Proceedings of the 39th International Free-Electron Laser Conference, FEL 2019 p.262-265- Abstract
Due to the stochastic nature of SASE radiation its longitudinal coherence is limited to a small fraction of the electron bunch. By pre-bunching the electrons before entering a radiator, the FEL radiation is ensured to have the same initial phase all through the bunch. Echo enabled harmonic generation (EEHG) is a technique that, by cleverly using two modulators and two dispersive sections, creates microbunches of electrons at a high harmonic of the seed laser used in the modulators. In this paper we will present some of the challenges of using this technique in combination with a strongly chirped beam and indicate a few ways to overcome said challenges.
