Abstract (englisch):

The key for a significant increase of the gyrotron efficiency is the development of an efficient multistage depressed collector (MDC) for the annular spent electron beam. During the past years, many different design approaches based on E×B drift concept have been theoretically investigated at KIT. The next step towards the experimental validation of such an MDC is the development of a prototype. The complexity of the mechanical design of the MDC is strongly dependent on the size of the electrodes, the manufacturing possibilities of individual parts, the electric field distribution, etc. Considering all those factors, an MDC system has been optimized in order to significantly reduce the manufacturing complexity of the prototype. As a result, a significant smaller and simpler conceptual design for the MDC system is presented.
