Two-bunch self-seeding for narrow-bandwidth hard x-ray free-electron lasers∗
It is well known that seeding can be used to produce narrow-bandwidth and fully coherent x-ray freeelectron lasers (FELs). Self-seeding, which uses an extra undulator to generate the seed pulse, is perhaps one of the most promising methods to accomplish this. In the hard x-ray regime with high-energy electrons, this method requires a large magnetic chicane to match the path-length delay of the ...
متن کاملZone Plates for Hard X-Ray Free-Electron Lasers
Hard x-ray free-electron lasers are novel sources of coherent x-rays with unprecedented brightness and very short pulses. The radiation from these sources enables a wide range of new experiments that were not possible with previous x-ray sources. Many of these experiments require the possibility to focus the intense x-ray beam onto small samples. This Thesis investigates the possibility to use ...

PACS. 61.10.-i – X-ray diffraction and scattering. PACS. 32.80.-t – Photon interactions with atoms. PACS. 36.40.-c – Atomic and molecular clusters. Abstract. – The ingenious idea of single molecule imaging by hard x-ray Free Electron Laser (X-FEL) pulses was recently proposed by Neutze et al. [1]. However, in their numerical modelling of the Coulomb explosion several interactions were neglected...
متن کاملX-ray free-electron lasers
In a free-electron laser (FEL) the lasing medium is a high-energy beam of electrons flying with relativistic speed through a periodic magnetic field. The interaction between the synchrotron radiation that is produced and the electrons in the beam induces a periodic bunching of the electrons, greatly increasing the intensity of radiation produced at a particular wavelength. Depending only on a p...
متن کاملA beam branching method for timing and spectral characterization of hard X-ray free-electron lasers
We report a method for achieving advanced photon diagnostics of x-ray free-electron lasers (XFELs) under a quasi-noninvasive condition by using a beam-splitting scheme. Here, we used a transmission grating to generate multiple branches of x-ray beams. One of the two primary diffracted branches (+1st-order) is utilized for spectral measurement in a dispersive scheme, while the other (-1st-order)...
