MATERIAL PROCESSING AND CHARACTERIZATION

Y

New developments in the modeling and analysis of radiation damage in materials

Energetic particles (including electrons, neutrons, ions and photons) are widely used to modify materials or to emulate extreme environments. Particle/solid interaction usually generates damage whose formation mechanisms and subsequent evolution must be precisely characterized. This symposium provides a forum to discuss recent progress in the modeling and analysis of radiation damage in materials.

Scope:

Energetic-particle irradiations are widely used both in the industry and in academic research laboratories to tune the physical properties (e.g. by ion doping) and microstructure of materials (e.g. nanopatterning, thin film growth, phase change) or to emulate radiation environments such as those encountered in space and nuclear reactors. Particle/solid interactions usually lead to (micro-)structural and/or chemical changes. In the case of controlled irradiation-induced material modifications, part of these changes may be deleterious as they can degrade the material properties (although there exists irradiation-defect engineering) and they are therefore considered as damage. On the other hand, when energetic particles are used to reproduce specific radiation environments, changes are purposely generated to evaluate the radiation-resistance of materials. Yet, in both cases, i.e. whether the damage is desired or suffered, its accurate characterization and fine description is a mandatory issue to tackle for the development and optimization of advanced materials and irradiation processes.

In this framework, the recent years have seen the development and improvement of experimental characterization techniques, computational tools, theoretical models and codes for data fitting. In addition, new ways to generate, emulate and simulate damage, either via computational methods or using innovative platforms delivering particle beams, are constantly being developed. The aim of this symposium is therefore to provide a forum for researchers to present and discuss new developments and findings in the generation, observation, description, and modeling of irradiation-induced damage in materials. Special focus will be given to techniques, protocols, and methodologies allowing damage quantification. The coupling of experimental and computational characterizations will also receive particular attention. Finally, recent progress in in situ measurements, small-scale testing as well as improvements of conventional techniques to investigate radiation damage will also be addressed. To finish, this symposium is cross-disciplinary on a wide range of materials including metals, semiconductors, and ionocovalent materials with different dimensionality (e.g. 0D quantum dots, 1D nanowires or tubes, 2D thin film materials and 3D bulk materials) and on a broad range of irradiation conditions, experimental techniques and computational simulations.
