The idea of regular scientific meetings of physicist involved in studies of ferroelectrics and phase transitions in Poland and Czechoslovakia followed inevitably from the success of first such event in Blazejewko in 1979. The Seminar was organized in collaborating of the Department of Dielectric of the Institute of Physics of Czechoslovak Academy of Sciences and Ferroelectric Lab of the Institute of Molecular Physics of Polish Academy of Sciences. The Seminars are an international forum for presentation of recent results, unconstrained discussions and initiating of joint studies.

Ad hoc workshops are small two days workshops organized by authors of the crystallographic software Jana2006. The topics and dates are selected by participants in Jana web pages. A workshop is organized as soon as an overlap in subscribed topics is found. The topics of the 17th workshop are as follows: (INT1) Simple 3d structures; (INT2) Simple 4d modulated structures; (DIS) Disordered structures; (RIG) Application of rigid body; (TW) Twinning. Program details will be given in the workshop page.

The goal of the workshop is that each participant will calculate crystal field parameters of the rare earth in a compound of his choice. The method can be applied to arbitrary local symmetry of rare-earth site.

This workshop explains and demonstrates the method of electron diffraction tomography. Using practical examples, it explains the whole process starting from electron diffraction data collection and processing, followed by solution of the phase problem and finished by refinement of crystal structures using either kinematical or dynamical theory.
