Abstract
A new concept for the collection of an electron beam, which is configured by an externally applied axial magnetic field, is presented. The two major advantages of this new idea are the significant increase of the collector efficiency and the reduction of the power absorption on the collector wall. To demonstrate the concept, an indicative collector design has been prepared for the hollow electron beam of the European 170-GHz 2-MW coaxial gyrotron for the international thermonuclear experimental reactor. The simulation shows that the efficiency of this advanced collector is more than 90%.
