of Inelastic Neutron Scattering using McStas and material dynamics
neutron scattering technique is a perfect tool to measure the
density of states, the intra-molecular and dispersion relations in
materials, complementary to x-rays due to different interaction
cross sections. Given the increasing complexity of the materials
studied nowadays, the use of computational tools has become
essential to complement and help in the understanding of the
experimental data. In particular, DFT and MD calculations are
indispensable to interpret measured neutron vibrational density of
states or phonon dispersion curves. Therefore the school will be
focused on showing how computational codes can be applied to
calculate experimental spectra. As such this school is at the
interface between computational and experimental scientists and we
intend to bring together both communities. The expected attendees
will be either scientists with a strong computational background and
collaborating with experimental groups (in particular neutron
scattering users) or experimentalists with some previous knowledge
of electronic-structure calculations and/or force-field based
simulations. Both will learn how to use existing modern tools to
compute the measured signal (including instrument effects) starting
from an initial structure, down to the neutron scattering intensity,
helping to bridge the gap between experiment and simulation.
MDANSE 2018 school intends to train neutron scientists to better
design new instruments, but also to make better use of the allocated
beam time. It has specialized scope (inelastic scattering, material
modelling) and covers many existing or planned neutron scattering
instruments. The school will not focus on the data analysis, but
rather on all aspects of simulation, from materials to instruments,
and present an integrated pipeline.
MDANSE 2018 is focused on the calculation of materials dynamics,
e.g. dynamic structure factor S(q,w) vibrational properties, using
both DFT and classical MD codes. This calculation will then be
forwarded to full virtual experiments of neutron scattering
spectrometers in order to produce realistic simulated data, such as
inelastic and quasi-elastic neutron scattering intensity. A set of
representative spectrometer descriptions will be proposed to
attendees, together with the so-called scattering kernels which
model the neutron-matter interaction.
This school is the continuation of MDANSE 2012 and 2014 at the ILL,
2016 in ISIS series. It also relates to previous neutron
scattering instrument simulation McStas schools/workshops in
The school targets scientists with confirmed knowledge in inelastic
scattering and/or materials modelling, whereas previous such schools
were more oriented towards beginners. It will consist mainly in
practicals and hands-on sessions.
This MDANSE event will build a bridge between the two communities:
materials and neutron scattering instrument modelling.

VirtualBox, running a custom Ubuntu 16.04 system with
Participants are requested to install VirtualBox on their
computer. We shall provide a USB key with a virtual machine
having all required software pre-installed. You need to make
sure you have about 30 Gb of disk space available on your
computer. It is best to have 8 Gb of physical memory.
- Install the "Extension pack"
- file is e.g.: Oracle_VM_VirtualBox_Extension_Pack-5.2.12.vbox-extpack
- Simply double click on it. This allows to use USB
devices (keys, disks...).
- Linux host system: open a terminal, type: sudo
adduser $USER vboxusers
- When gievn the USB key, double click the "ova"
icon. VirtualBox will then launch and add a new "virtual
machine" into VirtualBox main window (left panel). A
"VirtualBox VMs" folder will be created on your computer,
and the machine will be stored there as a set of files. Once
validated, importation take 5-10 minutes, and will use about
30 Gb of disk space.
- Make sure you check the 'Reinitialize MAC address'
to avoid network conflicts.
- Attach all of your CPU's to it to benefit from
- Attach half of your physical memory to it.
Installed software includes:
- Ubuntu 16.04 system, Mantid, McStas and associated tools
(cif2hkl, ...), ASE and PhonoPy, ABINIT, VASP, LAMMPS,
GROMACS, QuantumEspresso, Matlab (trial version), iFit,
LAMP, SpinWave, MDANSE (ex. nMoldyn)
