Abstract :
The 2.5D large-signal code TESLA-CC is a modification of the well-established klystron code TESLA to make it suitable for the 2D modeling of Coupled-Cavity Traveling-Wave Tubes (CCTWTs) by adopting the Curnow-circuit model for representation of the fields of an external coupled-cavity structure. We report the results of TESLA-CC modeling for an experimental Ka-band broadband CCTWT, called here as NRL-1. Performed in this work comprehensive numerical simulations and their wide comparisons with the measurements can be considered as a validation study for the code TESLA-CC.
