Workshop/school announcement

[Simon J. L. Billinge]

Dear Diffpy users....this is a "must not miss" school for people getting into nano and disordered materials research.  Please consider signing up and attending....

Dear Colleague,

We are pleased to announce ADD2026, the 6th edition of the School
and Conference on Analysis of Diffraction Data (ADD) in real-space:

https://workshops.ill.fr/e/add2026

co-organized by the European Synchrotron (ESRF) and the Institut
Laue-Langevin (ILL), and taking place:

                   11 to 16 January 2026

at the European Photon and Neutron (EPN) campus in Grenoble, France.

Building on the positive experience of the five previous ADD workshops
in Grenoble: ADD2011 (12-14 October 2011), ADD2013 (18-22 March 2013),
ADD2016 (7-11 March 2016), ADD2019 (17-22 March 2019) and finally
ADD2022 (16-21 October 2022), the 5-day programme of ADD2026 includes
2-1/2 days for the School followed by 2-1/2 days for the Conference,
basically the same format as for ADD2022.

The ADD2026 School and Conference aim to deepen the understanding and
to further the training of the various communities working on real-space
data analysis for neutron, x-ray and electron diffraction techniques.
Fourier transformation of diffraction data into real-space, traditionally
used for the structural determination of liquids and glasses, is now
widely employed for partially-disordered crystalline powder samples
and nano-structured materials in general.  Real-space analysis and
modeling techniques are also increasingly applied to single-crystal
samples exhibiting some local atomic disorder, and most recently to
short-range spin-spin correlations in disordered or frustrated magnetic
systems (in the case of neutron diffraction).

In general, real-space analysis of total-scattering data or "PDF-analysis"
provides a quasi-instantaneous snapshot of the local structure within
the sample, and is therefore sensitive to both static and dynamic atomic
and magnetic correlations, and hence complementary to the space-time
averaged structure provided by the well-known Rietveld refinement method
for diffraction data.

The scientific scope of ADD2026 covers many aspects of local versus
long-range atomic and magnetic order in a variety of materials having
fundamental and technological interests.  The School proposes pedagogic
lectures on real-space data-analysis techniques followed by 11 different
sessions of hands-on tutorials for training with various data-modelling
software packages: DiffPy-CMI, diffpy.mpdf, DISCUS, Dissolve, EPSR,
PDFgui, RMCProfile, Spinvert, Spinteract, Topas and Yell. Each ADD2026
School participant can choose 2 of the 11 tutorials to follow.

The Conference proposes 8 invited talks and 17 additional oral contributions,
as well as a poster session.

More detailed information, including on-line registration (opening soon)
and a preliminary programme, can be found on the webpage link given above.

Looking forward to seeing you in Grenoble,

The organizers:
   Brigitte Dubouloz (ILL)
   Daniel Chaney (ESRF)
   Stefano Checchia (ESRF)
   Gabriel Cuello (ILL)
   Henry Fischer (ILL)
