abstract = {X-ray crystallography is one of the main methods to
determine atomic-resolution 3D images of the whole spectrum
of molecules ranging from small inorganic clusters to large
protein complexes consisting of hundred-thousands of atoms
that constitute the macromolecular machinery of life. Life
is not static, and unravelling the structure and dynamics of
the most important reactions in chemistry and biology is
essential to uncover their mechanism. Many of these
reactions, including photosynthesis which drives our
biosphere, are light induced and occur on ultrafast
timescales. These have been studied with high time
resolution primarily by optical spectroscopy, enabled by
ultrafast laser technology, but they reduce the vast
complexity of the process to a few reaction coordinates. In
the AXSIS project at CFEL in Hamburg, funded by the European
Research Council, we develop the new method of attosecond
serial X-ray crystallography and spectroscopy, to give a
full description of ultrafast processes atomically resolved
in real space and on the electronic energy landscape, from
co-measurement of X-ray and optical spectra, and X-ray
diffraction. This technique will revolutionize our
understanding of structure and function at the atomic and
molecular level and thereby unravel fundamental processes in
chemistry and biology like energy conversion processes. For
that purpose, we develop a compact, fully coherent,
THz-driven attosecond X-ray source based on coherent inverse
Compton scattering off a free-electron crystal, to outrun
radiation damage effects due to the necessary high X-ray
irradiance required to acquire diffraction signals. This
highly synergistic project starts from a completely clean
slate rather than conforming to the specifications of a
large free-electron laser (FEL) user facility, to optimize
the entire instrumentation towards fundamental measurements
of the mechanism of light absorption and excitation energy
transfer. A multidisciplinary team formed by laser-,
accelerator,- X-ray scientists and as well as
spectroscopists and biochemists optimizes X-ray pulse
parameters, in tandem with sample delivery, crystal size,
and advanced X-ray detectors. Ultimately, the new
capability, attosecond serial X-ray crystallography and
spectroscopy, will be applied to one of the most important
problems in structural biology, which is to elucidate the
dynamics of light reactions, electron transfer and protein
structure in photosynthesis.},
