ABSTRACT:
A magnetron includes a cathode assembly which comprises a helically wound wire supported by a ceramic cylindrical member. Emissive material is located between adjacent turns of the conductor and connection is provided to the conductor via a rod and tube. When current is passed through the conductor (2), the emissive material (4) is directly heated.
