  • Abstract
    With the rapid development of broadcasting, communication and aviation industry, the study of vacuum electron devices has become the key issue of the researchers around the world. Being the heart of electron tubes and magnetrons, the cathode plays an important role in these devices. Two kinds of cathodes, rare earth oxide-Mo cermet (RE2O3-Mo in brief) secondary emission materials and Scandia doped tungsten matrix impregnated thermionic emission materials have been studied.
