A method is disclosed to fabricate a cathode electrode for a continuous wave magnetron so that the resulting product is relatively free from random frequency modulation and frequency "pushing". The method generally comprises the steps of forming, from a slurry containing comminuted tungsten and thorium hydride, a cathode electrode of the desired shape and heat treating such cathode to remove all volatile elements and ultimately to form a cathode electrode made up of an eutectic mixture of tungsten and thorium particles of tungsten. |
