Abstract (englisch):
This presentation reports on the 2019 status and focus areas in the development of an advanced gyrotron for the European DEMOnstration Fusion Power Plant (EU DEMO). As specified within the EUROfusion Work Package Heating and Current Drive (WP HCD), the requirements for the gyrotron are as follows: (i) ≥ 2 MW of RF output power at frequencies ≥ 200 GHz; (ii) a total efficiency ≥ 60 %; (iii) the options for multiple-purpose/multi-frequency operation and fast frequency step-tunability within a limited bandwidth of approximately ± 10 GHz. To meet those targets, the R&D activities are organized in five main branches: (1) the experimental verification of the advanced coaxial-cavity gyrotron technology at long pulses; (2) the development of an advanced coaxial-cavity gyrotron that meets the EU DEMO requirements; (3) the fundamental research on multi-stage depressed collectors for enhanced energy recovery; (4) the development of large broadband diamond windows to allow for fast frequency tunability of the gyrotron: (5) the studies on further innovations and improvements of critical gyrotron components and tools in view of optimization of performance, reliability, and industrialization.
