High power and high frequency applications of diamond — •Dirk Strauß — KIT Karlsruhe, Deutschland

Content of this tutorial is the presentation of basic properties of polycrystalline as well as single crystalline CVD diamond in high frequency (GHz-THz) and high power (MW) applications with extreme low microwave losses. Starting with growth conditions of diamond, optimization of dielectric and thermal properties up to implementation in diamond window assembly structures for multi-frequency applications (step tunable and Brewster windows) the complete development process and the state of the art today will be presented. Main applications of this field are heating and diagnostic systems in nuclear fusion reactors, accelerator and laser devices, where such windows can be implemented with outstanding physical properties.
