RESEARCH ON NOISE IN CROSSED-FIELD GUNS.
Abstract
Additional measurements on the dependence of noise figure upon the various operating parameters are described. Noise measurements in the complete frequency band and reduction of noise figure by stub tuning at the output terminal of the tube are discussed. Data from the reflected power seems to indicate that there is a slight shift in frequency between hot and cold test VSWR measurements. The correlation between noise figure and VSWR measurements is discussed. Some Kino gun features are investigated experimentally by operating the tube at different values of the magnetic field; other parameters are changed accordingly. This requires then a velocity jump at the gun exit so that the electrons drift at the synchronous velocity in the interaction region. (Author)
