Title: The study of ultrafast phenomena in applied science at the ELI Beamlines facility

Abstract: The presentation introduces the activities of the research programme for Applications in Molecular,
Bio-medical and Material (MBM) science at the ELI Beamlines (ELI BL) facility in the Czech Republic.
The MBM research programme develops methods for time resolved studies (spectroscopy, diffraction
and imaging) of ultrafast phenomena in physics, chemistry and biology utilizing pulsed lasers and
laser driven X-ray sources.
The ELI BL facility is part of a European Strategy Forum for Research Infrastructures (ESFRI) plan to
build a new generation of research facilities in new EU member states and offer these to an
international user community. The scientific activities at ELI BL will be based on the utilization of four
unique short pulse lasers. Each one with a unique combination of pulse profile, repetition rate and
intensity. Part of the ELI BL mission is to develop a new generation of laser driven light sources for
ultrashort pulses covering the VUV to gamma-ray energy range based on plasma effects in gases and
solids as well as relativistic electron acceleration. The sources under development are: A Higher
Harmonics Generation (HHG source), a Plasma X-ray source, a Betatron and inverse Compton
scattering source and a laser driven undulator X-ray source (LUX). All sources have the potential to be
used in combination with beams split off from their corresponding drive lasers for unique pump-probe
experiments. In contrast to the situation at accelerator base light sources, like synchrotrons and FELs,
the fact that the pump pulse can be split off from the same laser pulse that generates the X-ray pulse
provides an intrinsic synchronization between the pump and the probe pulses.
