Omniguide traveling-wave tube structure testing with a 120 KEV electron beam
San Diego, CA(2009)
Abstract
Compact, efficient, high-bandwidth and high-power mm-wave sources are essential for many applications in secure communications, environmental monitoring, imaging, spectroscopy for remote sensing in nonproliferation, and basic research such as radio astronomy. Commercial microwave tube amplifiers are available at frequencies up to only 100 GHz (W- band) and have to trade off maximum output power against bandwidth. A wide-band mm-wave traveling-wave tube (TWT) amplifier development is underway at Los Alamos National Laboratory. In this presentation we will report the design of the omniguide TWT structure, the results of the cold test measurements, and preliminary results of the beam transport through the structure and the gain experiment with the structure driven at 94 GHz.
