DEVELOPMENT OF A MILLIMETER WAVE GENERATOR USING A FIELD EMISSION CATHODE,

Abstract

A six-month feasibility study is reported which has two basic objectives: first, to develop and test an X-band oscillator with a field emission cathode; and second, to determine if an electron gun using a field emission cathode can be de veloped which will generate an electron beam of suitable diameter and conductance for a 70 gc oscillator. A floating drift tube klystron was chosen as the most suitable device. Two 1-3/4 mode tubes were designed and tested. The beam conductance required to start the oscillators agreed well with the calculated starting conduct ance, and a peak output power of 16 watts was obtained. Several electron gun designs were in vestigated and results indicate that a beam of less than one fourth millimeter diameter, with three times the beam conductance required to operate the X-band oscillators, can be obtained with a field emission cathode. These charac teristics wou-e adequate for a floating drift tube klystron operating at 70 gc. (Author)
