RESEARCH ON NOISE IN CROSSED-FIELD GUNS.
Abstract
The design criteria for the low-noise crossed-field amplifier are discussed. The assembly drawing of the device is given and the various parts used in the device and their functions are discussed in detail. It is found that by selection of appropriate dimensions for the insulators (which withstand the sole-anode voltage) and the BeO parts (which provides sufficient cooling for the losses), reasonably good insertion-loss characteristics can be achieved. In noise figure calculations it is found necessary to consider the propagation of all the waves; consideration of the growing wave only yields values of calculated noise figure less than those obtained by considering all the waves. This difference depends upon the gain of the amplifier. (Author)
