Report on modelling and materials

The WP8 aims at the design of advanced materials and collimators to allow for higher beam power in state-of-the-art accelerator facilities. Task 8.2 in particular focuses on the research, development, production, characterization and testing of novel materials for advanced thermal management applications primarily devoted to future Phase II Collimators, but having the potential to be applied to a much broader spectrum of applications. A broad variety of materials has been studied, produced and characterized, including metal-diamond composites such as Copper-Diamond, Silver-Diamond, Molybdenum-Diamond as well as Molybdenum-Graphite composites with very promising results. Advanced numerical simulation techniques have been used to study the behaviour of these, as well as more traditional materials under the effect of very intense, highly energetic particle beams. An intensive testing programme is being deployed to verify their behaviour under extreme conditions.
