Yield control in multisection helix traveling-wave tubes (TWTs) is a fundamental issue in the manufacturing process. Assuming TWT small-signal gain as a design goal, yield degradation due to the helix-pitch manufacturing error is investigated in depth. The relevant contribution of the sections with lower helix pitch is studied. Oil the basis of the obtained results, indications,for defining the helix-pitch profile that provide a better compromise between yield and performance are given. (c) 2005 Wiley Periodicals, Inc.
