APPLIED RESEARCH ON A HIGH-POWER MILLIMETER-WAVE GENERATOR.
Abstract
The purpose of this program is to demonstrate the feasibility of generating very high power, specifically, 100 kw peak and 1000 watts average at 100 Gc, by means of an O type backward-wave oscillator operating at very high voltage. A discloaded waveguide which operates from 90 kv to 200 kv was selected as the circuit for the backward wave oscillator. A 900 to 1 convergence ratio electron gun was developed. This perveance 0.125 x 10 to the -6th power electron gun was focused through a .062 in. diameter beam hole with over 96% transmission at 190 kv. The power density in the beam was 280 megawatts per square cm. Peak power of 107 kilowatts was measured using a calorimeter as a power standard. An average power of 324 watts was measured using the calorimeter. Both of these power levels exceed any other known values of power at a frequency of 100 Gc. (Author)
