Multiple Beam Grid Tube Development

Several accelerator projects are under construction or planned that require RF sources in the UHF frequency range. Unfortunately, there are few high-power RF sources available. Klystrons and solid-state sources are large, expensive, and inefficient in this frequency range. Gridded tubes are compact, low cost, and highly efficient; however, single beam devices are limited in output power. This presentation describes research in progress to develop multiple beam, gridded tubes providing higher power<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup>.
