Abstract :
The Multiple-Beam (MB) Inductive Output Tube (IOT) has been proposed for UHF applications requiring from 500 kW to 1 MW of average power. Our team of Scientists and Engineers are developing and validating a suite of computation tools for the design of these advanced devices. The cornerstone of this effort is the development of a circuit-based beam-loading model in the Finite Element Electrostatic PIC code MICHELLE [1]. Results of our validation effort will be shown. We are also applying these tools, along with codes TESLA [2] and Analyst [3], to a design study of a number of five, six, ten and twelve-beam MB IOTs, for average power levels ranging from 500 kW to 1 MW. Results from this effort will be described.
