Electron Beam Semiconducting S-Band Amplifier.
Abstract
S band, Electron irradiation, Reliability, Hybrid systems, Solid state electronicsElectron beam semiconductor amplifiers, DesignThe construction and testing of the life test tubes which was begun in the last reporting period was continued. Five tubes were processed with a total of ten diodes. Sheet beam dispenser cathodes were designed and ordered. A new diode failure mechanism appeared in the presence of the electron beam which does not seem to be related to previously solved problems. None of these devices were able to be plated on extended life test. Design procedures became available from other programs during the period for tuned resonant circuit amplifiers which relate physical design parameters to bandwidth and power output. Accurate S-band designs were then calculated which indicate achievable performance. Cold testing took place of a radial transmission line resonator suitable for use in a tuned amplifier at 3.2 GHz.
