Design of slowwave broadband gyro-TWT with a bifilar helix circuit

Abstract

By analyzing the Maxwell-Vlasov equations, a beam-wave dispersion relation has been derived for a gyro-TWT incorporating a bifilar helix slow-wave circuit. The linear gain has been examined in the slow-wave region to characterize anticipated performance. Results will be compared with that of the gyro-TWT with dielectric clad waveguide circuit.
