Abstract :
A novel gun structure for modulation of a cathode-ray beam with frequencies from dc to 12 GHz has, been developed. The paper describes the new design and presents performance data. The new gun is the result of the extension of work most recently reported on in a paper entitled "Nanosecond Beam Intensification for Cathode-Ray Tubes" in the March, 1966, issue of IEEE Transactions on Electron Devices. Essentially, the gun consists of a 50-ohm coaxial structure in which the cathode and a modulating grid are arranged to form part of the inner and outer conductor, respectively. The gun can be used with conventional magnetic or electrostatic focusing and deflection systems.
