The development of high efficiency, Multiple Beam Inductive Output Tubes (IOTs) with efficiencies greater than 80% would substantially reduce the operating costs of next-generation particle accelerators. We discuss the development of a multiple-beam

Traditional application of multipactor coatings applied with sputtering techniques to high-power RF windows typically performs well when applied to sintered powder ceramics. Unfortunately, sputtered coatings do not adhere well to crystal materials, s

The design of a 10 MW, 1.3-GHz annular beam klystron for accelerator applications has been analyzed in detail and optimized. Concerns about the diocotron instability were addressed by simulations, which showed the growth to be negligible. The calcula

In this paper, the design of a 10-kW/28-GHz gyrotron is presented. The main characteristic of the new gyrotron is the emitter ring, which is assembled from twelve individually supplied emitters based on controlled-porosity reservoir (CPR) technology.

The research reported here was aimed at development of an L-band multi-beam klystron with parameters relevant for ILC. The chief distinction of this tube from MBKs already developed for ILC is its low operating voltage of 60 kV, a virtue that implies

This program developed a 10 MW, pulsed, Annular Beam Klystron (ABK) for accelerator applications. This is an alternative RF source to multiple beam klystrons MBKs), which are more complex and considerably more expensive. The ABK uses a single, annula

Controlled porosity reservoir cathodes offer significantly improved performance over conventional impregnated cathodes. Optimized performance requires additional design to achieve reduced barium deposition on adjacent surfaces, increased lifetime, an
