Anodic Oscillation in Glow Discharge (II) The Gap Properties, Analogous to an Ordinary Electric Oscillator with Linear Circuit Elements

Abstract

The gap of the anodic oscillator tube is described as a special type of dynatron oscillator. The characteristic capacitance C₀ and inductance L₀ of the oscillating gap, being the order of 10⁻³μf and 10⁻¹∼10⁻²H respectively, are determined from the frequency change caused by adding externally a variable condenser or inductor. The dynatron-type negative conductance comes principally from the transient ionization in the anode sheath. The behaviors of the quantities characterizing the oscillation such as the amplitude, the frequency, and the wave form can be explained systematically. The brief discussion about the physical meaning of C₀ and L₀ is also given.
