Gyrotron development
For the development and research of high-performance microwave tubes, the possibilities for experimental verification are crucial. The IHM has the world's most modern, flexible and powerful facility for this purpose. It consists of two independent test benches, the first of which has been in successful operation for many years and the second test bench (FULGOR) was put into operation in 2022.
The interaction analysis and components group of the IHM mainly develops simulation tools to realistically describe the behaviour of a gyrotron. The propagation of an accelerated electron beam in a magnetic field, its interaction with a microwave field and finally the impact of the electrons on the collector are taken into account. Further simulation programs deal with the design of quasi-optical components for the optimal coupling of the microwave out of the gyrotron.
