Large-Signal Code TESLA: Current Status and Recent Development
Abstract
The optimization and design of new high-power, high-efficiency klystron amplifiers relies increasingly on effective nonlinear simulation tools. One such tool is the large-signal code TESLA, which was successfully applied for the modeling of single-beam and multiple-beam klystron devices at the Naval Research Laboratory and which is now used by number of U.S. companies. TESLA is a highly efficient fully electromagnetic two-dimensional code that solves self-consistently the electromagnetic field equations (including fields inside beam tunnel and cavity fields) and three-dimensional relativistic equations of electron motion. TESLA allows one to model with high accuracy the main physics of complex devices with multiple resonant cavities and multiple electron beams. A typical TESLA run takes only a few minutes to complete for most problems under consideration, making the code useful as a design tool. This work presents the current-status and the latest advances in the development of the large-signal code TESLA, mainly used for the modeling of high-power single-beam and multiple-beam klystron amplifiers.
