TL;DR: In this paper, the general electromagnetic properties and design methodology for serpentine/folded-waveguide (FW) amplifiers are presented, and a comparison between code prediction and experimental data is made.
Journal ArticleDOI
A Computationally Efficient Two-Dimensional Model of the Beam–Wave Interaction in a Coupled-Cavity TWT
TL;DR: In this article, a 2D model of the beam-wave interaction in coupled-cavity traveling-wave tubes (CC-TWTs) has been developed, which provides self-consistent time-dependent solutions of Maxwell's equations together with a fully relativistic solution of the electron equations of motion.
Journal ArticleDOI
Large-Signal Multifrequency Simulation of Coupled-Cavity TWTs
David Chernin,Thomas M. Antonsen,Igor A. Chernyavskiy,Alexander N. Vlasov,Baruch Levush,Rasheda Begum,James R. Legarra +6 more
TL;DR: In this article, a steady-state large-signal model of coupled-cavity traveling-wave tubes is described, in which the input and output signals are periodic functions of time that may be represented by Fourier series of finite length.
Journal ArticleDOI
Parallel Simulation of Independent Beam-Tunnels in Multiple-Beam Klystrons Using TESLA
Igor A. Chernyavskiy,Simon J. Cooke,A.N. Vlasov,Thomas M. Antonsen,David K. Abe,B. Levush,Khanh T. Nguyen +6 more
TL;DR: In this paper, an extension of the TESLA to model multiple-beam klystrons (MBKs) in which interaction parameters may vary significantly from beamtunnel to beam-tunnel is presented.
