Investigations on the Depression Voltage Concept for the Next Generation of EU Gyrotrons

Le résumé fourni par la source

Gyrotrons are high-power vacuum electron tubes essential for plasma heating in magnetically confined thermonuclear fusion applications. In particular, they are used for Electron Cyclotron Resonance Heating (ECRH), Current Drive (CD) and Collective Thomson Scattering (CTS) plasma diagnostics [1]. The demand for ECRH power is continuously growing, as demonstrated by ITER, which requires 40 MW of heating power in its baseline and plans to upgrade to 67 MW in a later operational phase [2]. The demand for more ECRH power drives the development of a new generation of gyrotrons. Those gyrotrons shall not only deliver an output power above 1 MW and an improved efficiency better than 50 % but also shall feature simpler designs, which help to reduce both manufacturing and operational costs. To achieve this ambitious goal, numerous challenges must be addressed. Systematic studies on the simplification of components and their resulting influence on other gyrotron parts are essential, as all components—including the Magnetron Injection Gun, beam tunnel, cavity, quasi-optical system, collector, and auxiliary systems like the superconducting magnet-are interdependent.
