Progress with DIMOHA for fast time-domain simulations of traveling-wave tubes

摘要

We presented at previous IVEC conferences a new model for traveling-wave tubes (TWTs). Since then, we used this model to build the DIMOHA algorithm as an alternative to current particle-in-cell (PIC) and frequency domain codes. Its validity is assessed against these codes and against measurements from several TWTs. We present simulations for an 80 watts TWT in Q band presently in development. An industrial version of DI-MOHA is under construction for the design and characterization of TWTs.
