Abstract :
A sheet beam traveling-wave tube amplifier is currently being developed under the DARPA HiFIVE program. The device is designed to achieve over 50 W output power at 220 GHz with a power-bandwidth product exceeding 1,000 W-GHz. This paper will report on the design and fabrication status of the electron gun, RF circuit, and RF window with emphasis on simulation of beam-wave interaction using the MAGIC-3D code.
