Abstract : A one-dimensional large-signal analysis computer code for Helix traveling-wave tubes was developed. The program is based on the theory developed by J.E. Rowe and M.K. Scherba. The program was written in FORTRAN 77 and implemented on an HP-1000 computer at Teledyne MEC in Palo Alto CA. The program is well documented and can accommodate attenuators, severs, velocity changes, linear velocity tapers, and multiple input signals. Two Teledyne MEC tubes were simulated with the program and the results were in very good agreement with experimental data. Large-signal analysis programs are widely used by the microwave tube community to predict the performance of helix traveling-wave tubes. These nonlinear programs allow an engineer to optimize a tube design without building several prototype tubes. Unfortunately, currently available programs are complex and poorly documented. The purpose of this project is to provide a structured, well documented large-signal analysis program to the scientific and industrial community.
