Abstract

Comparisons between predictions of the NRL large signal codes CHRISTINE and TESLA-FW and measurements of small signal gain of NRL´s G-Band serpentine waveguide TWT are presented. Results of a sensitivity study of the effects on gain of the circuit dispersion allow us to identify the most critical physical circuit dimensions for TWT design and to quantify required circuit fabrication tolerances.
