The growing energy demand, set to increase by 37% by 2040, and the reduction of greenhouse gases are two key reasons why the energy landscape needs to be less reliant on fast-depleting fossil fuels. In this frame, Nuclear Fusion represents an option by being a nearly unlimited, safe and CO2-free friendly energy source. In order to reach and support the required conditions such that nuclear fusion reaction can occur, a gas mixture (deuterium and tritium) needs to be confined, e.g. through strong magnetic fields, and heated using microwave systems operating at the cyclotron frequency. Such systems shall meet several requirements from both the physics and the engineering point of view and make use of diamond disks grown by Chemical Vapor Deposition (CVD). In this paper we present an overview of the applications of such disks in components know as diamond windows, for both present machine and ITER, and future power plants.
