High-Efficiency, High Average Power, Multiple Beam Inductive Output Tubes

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 IOT that employs a third harmonic drive component on the grid to achieve efficiencies greater than 80%. We discuss a novel input coupler, grid design, and simulation of the output cavity. This presents a path forward to the design and production of such high efficiency IOTs.
