The general objective of this work group is to provide information on methods and applications of neutrons on hot topics - e.g. in the energy or information sector and material science - to the community of crystallographers. We also would like to offer practical guidance to users who whish to use neutrons but have questions like “How do I apply for beam time?”, “In what time scale can I expect to do my experiment?” and so on.
In intervals of about two or three years, the work group offers courses and workshops to strengthen the exchange of information between all scientists interested in or already using neutrons.

This workshop will take place as online satellite of the DGK 2022 in Munich from 2021/03/17 in the afternoon to 2021/03/18.
Due to the still difficult pandemic situation, the optional guided tour through the neutron source FRM II of the Heinz Maier-Leibnitz Zentrum (MLZ) nearby at Garching will not take place. We are sorry about that.

The workshop addresses young scientists and those who are interested in the use of neutrons for studies on nowadays topics in solid state physics, solid matter chemistry, biology, mineralogy, geo sciences, material sciences and so on. Similar to previous workshops, the focus of this event is on techniques of diffraction, imaging and spectroscopy with neutrons as well as worked out examples on current topics.

Neutron Scattering is a very powerful method to investigate novel materials. Especially when focusing on magnetic properties or light atoms, neutron scattering is often the first-choice method. As neutron wavelength and neutron energy are simultaneously in the range of interatomic distances and nuclear or magnetic excitations, neutron scattering has proven to be a key technology in materials science. We intend in this workshop to teach the basic techniques to the participants. This is essential to allow them to make the best use of these expensive large-scale facilities during their future career.

Teaching the use of state-of-the-art data evaluation programs will round up this workshop.

Topics are Neutron Sources, Dynamic Structure Factor Simulations, Inelastic Neutron Scattering, Biocrystallography, Diffuse Scattering, Magnetic Space Groups, Direct Methods, Combined Methods, Neutron Polarimetry, Neutron Imaging, Refinement Techniques, Single Crystal Refinement using JANA2006, Fullprof Powder Diffraction Refinement.

with the following Speakers: Stephan Allenspach (Geneva/PSI), Margarida Henriques (Prague), Anders Kaestner (PSI), Marc Janoschek (PSI), Astrid Schneidewind (JCNS@MLZ), Martin Meven (RTWH, JCNS@MLZ), Sebastian Mühlbauer (TUM), Reinhard Neder (Erlangen), Valodja Pomjakushin (PSI), Jürg Schefer (PSI), Tobias Schrader (JCNS@MLZ), Markus Strobl (PSI), Yaroslav Filinchuk (UCLouvain)

Funding and Support: This workshop is organized jointly by the German Crystallographic Society (DGK, AK7) and the Swiss Society for Crystallography (SGK) with kind support from the ECM32 organizing committee (Dr. K. Hradil), RWTH Aachen, Paul Scherrer Institute and SINE2020.

The organizers are Jürg Schefer (Paul Scherrer Institute, Switzerland) and Martin Meven (RWTH Aachen University and JCNS at Heinz Maier-Leibnitz Zentrum, Germany)

Nowadays challenges in physics, chemistry, biology and material sciences often require crystallographic / structural studies that combine smartly various scattering methods using complementary synchrotron, neutron, electron or ion radiation. The workshop consists of two parts: in the first part, the peculiarities of the different kinds of radiation and their generation be discussed including an overview of the corresponding large scale facilities and the kind of methods they offer for structure analysis. In the second part, focusing on applications, experienced scientists will give an insight into the unique information they gain by merging the complementary methods. The following topics are planned:

• quantum phenomena/correlated systems (magnetism and superconductivity)
• macromolecular and biological studies (life sciences)
• functional materials for energy research
• etc.

The workshop will take place from Sept. 19th 2018 afternoon (16:00h) to Sept. 20th 2018 until lunchtime (13:00h). In addition, an optional guided tour through the Heinz-Maier-Leibnitz research reactor FRM II in the afternoon of Sept. 20th is planned at 15:00h. Please note that participation in the guided tour requires a registration until August 31rd latestly. The event is organized by the working group “Neutron Scattering” of the German Society of Crystallography (DGK). A registration to the SNI conference is not required to participate in this workshop. The workshop is located on the TUM campus near the location of the SNI conference.
