Fusion power may offer a long-term energy supply with an uninterrupted power delivery, a high power-generation density, and no greenhouse gas emissions, contributing to preventing the worst effects of climate change and making an enduring contribution to future energy supply. However, the intense conditions inside a fusion power plant (extreme temperatures and high magnetic fields necessary for nuclear fusion) call for addressing several potential problems. These include the development of new materials with extremely high heat tolerances and low enough vapor pressure and the design of mechanical structures that can withstand the electromagnetic force generated as well as feedback controllers to measure and counteract the unstable modes of evolution of the plasma, to name a few. The future of nuclear fusion as an efficient alternative energy source depends largely on techniques that enable us to control these instabilities. Mathematical modelling and physical experiments attempt to overcome some of the hindrances posed by these complexities. This book provides a comprehensive overview of the current state of the art in this fascinating and critically important field of pure and applied physics, mathematics, and engineering, presenting some of the most recent developments in theory, modelling, algorithms, experiments, and applications.

The multistage depressed collector (MDC) shall be one of the key technologies to achieve the required gyrotron efficiency in the DEMOnstration fusion power plant. For the first time, this work presents a comprehensive study of possible gyrotron MDC concepts. Concepts, only using axisymmetric E- and B-field components are shown to be insufficient. Instead, promising concepts using the E×B drift are proposed. A detailed study of a novel MDC concept using an azimuthal electric field is presented.
