| Annotation | The paper describes the results of the experimental research of the volt-ampere characteristics of the three-electrode electron gun. Such systems are widely used in the electron-ray devices meant for getting visible image on the screen, and in microwave devices, such as TWT, BWT, as well. On the basis of the experimental results practical recommendations of how to choose the optimal voltage regimes on the focusing electrodes were made, which allows to form paraxial axially-symmetric beams with the diameter in crossover about 0.05-0.5 mm and beam current up to 30 mA. |
