Abstract
An electron beam collector for transit time tubes, in particular traveling wave tubes, includes a plurality of metallic electrodes which surround the electron beam and which are spaced from one another by insulating bodies. The spacing components are firmly and preferably directly connected to the electrodes which they serve to space. The electrodes are, in each case, embraced by a sleeve which has a thermal coefficient expansion that is small in comparison to the electrodes and matched to that of the spacing components.
