Abstract

PURPOSE:To perform a surer control of the potential distribution in the opening part of an electrode and improve a reduction of return electrons and efficiency of collectors, by providing feather shaped protrusions in at least one electrode opening part of the collector consisiting of at least two electrodes with a different potential. CONSTITUTION:At opening parts of the second and third electrodes 13, 14 in a collector with at least two different potentials, for instance, four-stage depressed collector, feather-shaped protrusions 17, 18, 19 are provided. In this way, when an incident electron beam from a high frequency circuit part to the collector part is seized by each of the collector electrodes, a distribution of potential in the electrode opening part can be surely controlled to improve a reduction of return electrons and efficiency of the collector.
