| Abstract: | Properties of secondary emission and thermo - ionic emission, sinter contractive coefficients and atmosphere exposure characteristic for cathodes of molybdenum cathode doped with RE oxides have been measured. Microstructures of the sinters have been studied using SEM. As results, the suitable percentage of RE oxides in the cathode should be between 20% and 25%. |
