ABSTRACT:
Disclosed is an multiple-beam electron tube built around an axis (Z). These electron beams go through at least one resonant cavity (10) coaxial with this axis (Z). The beams are contained on both sides of the cavity in drift tubes (3) that end in the cavity in lips (5'), facing each other in the cavity. The spacing between two facing lips is not constant. Application especially to multiple-beam klystrons with improved output.
