LOW-LEVEL, CROSSED-FIELD NOISE STUDY.
Abstract
Experimental investigations of low-frequency electron tube noise are discussed. The work was done using experimental diodes with a coaxial configuration. The cathode is centrally located and surrounded by a concentric anode, split longitudinally into two equal sections. A magnetic field was applied colinear with the cathode. The investigation was confined to values of anode potential and magnetic field strength so that the experimental tubes were well beyond the Hull cut-off value at all times. The experiments were oriented primarily toward investigation of millivolt level oscillations in the frequency range of 0.5 to 10 megacycles. These oscillations are believed to be related in some manner to noise encountered in crossed-field microwave tubes. The mechanism of the oscillations is, as yet, unknown. (Author)
