Abstract

In the present article a new concept for the collection of an electron beam which is configured by an externally applied magnetic field is presented. The two major advantages of the new idea are the significant increase of the collector efficiency and the reduction of the power consumption on the collector wall. For the demonstration of the new concept a collector has been designed for the hollow electron beam of the European 170 GHz, 2 MW coaxial gyrotron for ITER. The simulation shows that the efficiency of this advanced collector is more than 90%.
