概要
- 論文の詳細を見る
The relations between the electron emission, the electrical conduction and the noise of the oxide coated cathode have been studied. The Richardson plot of the conduction current showed two straight line regions. The temperature dependence of the conduction current was found to be the same as that of the emission current, and the density of the former was a few times larger than that of the latter. The noise current accompanying with the conduction current showed sharp increase when the conduction current saturated. This is owing to the disappearance of the space charge in the pore. From these experimental results the pore conduction mechanism of the oxide-coated cathode was ascertained.
