Abstract :
A code for a fast 1-dimensional model is under development for the simulation for the beam-wave interaction in the traveling wave tube amplifier (TWTA). The code is based on a Lagrangian algorithm. The input parameters are modified to extend the code validity to structures different from angularly symmetric structures. The preliminary results for the output power and gain for the double corrugated waveguide (DCW) TWT at 225 GHz are compared with particle in cell (PIC) simulations.
