Proceedings of the 20th international workshop on inelastic ion-surface collisions (IISC-20), Wirrina Cove, Australia, 16th-21st of February 2014

The research on inelastic ion–surface collisions has developed over the last few decades into a variety of fields and covers energy loss of particles at surfaces, charge exchange processes, electron, photon and secondary ion emission due to particle impact on surfaces, defect formation, surface modification and nanostructuring, laser induced desorption, scattering of atoms, ions, molecules and clusters, sputtering and fragmentation, cluster and ion formation in SIMS and SNMS and highly charged ion beams. The understanding of the nature of ion-surface collisions has led to the development of many surface analytical and microscopic techniques. These techniques are used for surface and structural analysis, and surface modification in a large number of laboratories all over the world. Development of a large scale technology like nuclear fusion would not exist without the fundamental understanding of ion-surface collisions. The IISC workshops bring together researchers from different fields and facilitate the discussion of fundamental research, applications, and developments of new fields. Examples of new fields developed in recent years are guiding of ions in capillaries, surface channelling, and surface diffraction. These fields have been developed and have started to find their way into tools for analysis and material modification.
