Abstract

The knowledge and the control of fabrication tolerance are key issues to get the required traveling wave tube performance. The comprehension of the factors that mainly determine a yield degradation is required to avoid higher costs in the manufacturing process. This paper proposes a method to improve the yield of multi-section helix traveling wave tubes before the fabrication. Small-signal gain performance goal is assumed as the design target.
