he unique features of Neutrons make them a valuable tool
for many crystallographic studies on hot topics in physics,
chemistry, biology and material sciences. Their interaction with
nuclei yields not only high penetration depths but also interaction
strengths that differ significantly from the those well known
for X-rays, e.g. some light elements (H, O) show relative large
scattering cross sections compared to many heavy elements
while neighbored elements can differ strongly. Therefore,
Neutron imaging can be used to perform in situ radiography of
engines to study the different moving parts and liquids involved
in its operation. In the area of energy applications are the non-
destructive spacial reconstruction of the distribution of elements
inside new battery types during charge-discharge-cycles.
This can be combined with neutron diffraction studies on the
underlying chemical processes to develop new materials, e.g.
for Li-ion or sodium metal halide batteries [1, 2]. The sensitivity
of neutrons for light elements plays also an important role, e.g.
for the understanding of energy relevant compounds like ionic
conductors based on layered perovskites [3]. This holds true
also for for detailed studies on complex H bonds in minerals
(phosphates, silicates, etc.) or organicmatter/biological systems
in life sciences, e.g. antibiotics [4]. The magnetic moment
of neutrons allows detailed insights into magnetic order and
related phase transitions. This feature is widely used in recent
studies on multiferroics but also on modern high temperature
superconductors based on cuprates [5] or iron arsenides [6] and
played also an important role in the discovery of skyrmions [7].
The successful contribution of neutrons to various scientific
applications has been made possible by advances in methods
and instrumentation at existing neutron sources (e.g. in Europe
ILL, MLZ, ISIS, etc.) in recent years. This and the installation of
the new European Spallation Source ESS will support this trend
also for the future.
