Abstract
FERMI@Elettra comprises two free electron lasers (FELs) that will generate short pulses (τ∼25–200 fs) of highly coherent radiation in the XUV and soft x-ray region. The use of external laser seeding together with a harmonic upshift scheme to obtain short wavelengths will give FERMI@Elettra the capability of producing high-quality, longitudinally coherent photon pulses. This capability, together with the possibilities of temporal synchronization to external lasers and control of the output photon polarization, will open up new experimental opportunities that are not possible with currently available FELs. Here, we report on the predicted radiation coherence properties and important configuration details of the photon beam transport system. We discuss the several experimental stations that will be available during initial operations in 2011, and we give a scientific perspective on possible experiments that can exploit the critical parameters of this new light source.
Highlights
The dynamics and temporal evolution of matter down to sub-femtosecond time scales and atomic space scales are at the base of all chemical, physical and biological processes [1]
Interest has turned to short wavelength, free electron lasers (FEL) [6] which can produce light pulses with peak brilliance up to ten orders of magnitude higher than the pulses generated in present third generation synchrotron light sources and with photon energies spanning from the vacuum ultraviolet to the hard X-ray, i.e., from about 10 eV (120 nm) to 10 keV (0.12 nm)
Short wavelength FEL sources based upon “seeding” techniques in which the FEL pulse is initiated by a coherent radiation pulse generated by a conventional laser can produce output pulses with a well-defined temporal shape and intensity stability [8,9] that permits relatively straight-forward synchronization with external pump or probe lasers
Summary
The dynamics and temporal evolution of matter down to sub-femtosecond time scales and atomic space scales are at the base of all chemical, physical and biological processes [1]. Short wavelength FEL sources based upon “seeding” techniques in which the FEL pulse is initiated by a coherent radiation pulse generated by a conventional laser can produce output pulses with a well-defined temporal shape and intensity stability [8,9] that permits relatively straight-forward synchronization with external pump or probe lasers. These include temporally synchronized pump-probe experiments and others involving third harmonic radiation with photon energies as high as 900 eV
