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 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 کاملEvidence of high harmonics from echo-enabled harmonic generation for seeding x-ray free electron lasers.
Echo-enabled harmonic generation free electron lasers hold great promise for the generation of fully coherent radiation in x-ray wavelengths. Here we report the first evidence of high harmonics from the echo-enabled harmonic generation technique in the realistic scenario where the laser energy modulation is comparable to the beam slice energy spread. In this experiment, coherent radiation at th...
متن کاملTriple modulator-chicane scheme for seeding sub-nanometer x-ray free electron lasers
We propose a novel triple modulator-chicane (TMC) scheme to convert external input seed to shorter wavelengths. In the scheme high power seed lasers are used in the first and third modulator while only very low power seed is used in the second modulator. By properly choosing the parameters of the lasers and chicanes, we show that ultrahigh harmonics can be generated in the TMC scheme while simu...
متن کاملSp5-a the Challenge of X-ray Free-electron Lasers Structural Studies with X-ray Lasers
The history of the living world can be summarised as an elaboration of ever more perfect eyes within a Cosmos in which there is always something new to be seen (Teilhard du Chardin, 1955). Today, the bottleneck in the atomic resolution imaging of biological systems is a fundamental need for crystals. This limits the scope of detailed structural analysis to macromolecules and macromolecular asse...
