Abstract
The plane-diode model is used to study the equilibrium properties of a collisionless single-ended Q-machine over the most relevant parameter regions. A method is given for determining parameter points, or points of operation, which enables straightforward application of the theoretical results to specific experimental situations. A new disruptive effect is predicted which manifests itself in discontinuous changes in the equilibrium properties with a continuous variation of the neutral flux. As an example of application, a simplified analysis of the strong instability occurring at positive cold-plate biases is presented.Keywords
