Abstract:

A summary is given of the requirements for modern power cathodes. The technological development of impregnated cathodes, their emitting properties, their function, and chemical processes is presented. The composition of the emitting substance, the preparation of the cathode body, the procedure for measuring porosity impregnation, evacuation, and activation are described.Advantages are pointed out which render this cathode a powerful source of electrons with long service life and high resistance to high voltage gradients and residual gases.
