| 内容記述 | Temperature dependence over about 750-850°K of several peaks appeared on spectral dependence over 0.6-3.5eV of thermionic emission from (Ba-Sr) O cathodes was observed with activation. Three kinds of the cathodes which were easy or difficult to activate were used as specimens. From the experiment on the three kinds of the cathodes, it was found that there were three stages in the activation process of (Ba-Sr) O cathodes, though total thermionic emission always increased with activation through the whole process. In the activation stage I, with activation, the maximum temperature of 3.2-eV peak shifted to higher temperature, though work function decreased and the intensity of each peak increased. In the stage II, with activation, work function increased on the contrary, the intensity of 3.2-eV peak decreased showing negative effect, and the maximum temperature of 3.2-eV peak shifted to lower temperature and then to higher one. In the stage III, with activation, work function decreased, the intensity of each peak increased, and the maximum temperature of each peak remarkably moved to lower temperature. From these results, it was clearly known that the earlier two stages were the abnormal stages and only the stage III was the normal activation stage. | |||||||
