- Abstract
- The possibility to noise diagnostic of thermionic cathodes in electron-beam devices is considered in the present work. We would like to propose a universal noise informative parameter for a comparative estimation of noise properties of thermionic cathodes. It is shown that noise properties of dispenser cathodes are different for different parts of its surface. The authors have made and propose the surface-diffusion model of LF-noise of thermionic cathodes. The model is capable to predict the level and form of noise spectra.
