Current status and future trends in computer modeling of high-power travelling-wave tubes
- Communications and Power Industries, Palo Alto, CA (United States)
The interaction of a slow electromagnetic wave and a linear propagating electron stream has been utilized for many years for microwave amplification. Pulsed devices of high peak and average power typically are based on periodic, filter-type circuits and interaction takes place on the first forward-wave branch of a fundamental backward-wave dispersion curve. These devices have served as useful test vehicles over the years in the development of advanced computational methods and models. A working relationship has thereby developed between the plasma computation community and the microwave tube industry. The talk will describe the operational principles and design steps in modern, high-power TWT development. The major computational stages that the industry has seen over the last four decades in both 2-d and 3-d modeling will be reviewed and comments made on their relevancy to current work and future trends.
