Abstract

According to the invention, at least one magnet element is provided for generating a guide magnetic field such that the electrons are guided at a spacing from the elongated anode. At least one kicker magnet is provided for generating a kicker magnetic field such that the electrons are steered onto the elongated anode in the region of the kicker magnetic field. The kicker magnet is implemented as a permanent magnet.
