Abstract :
The efficiency of thermal electron emission is defined as the total motional power imparted to emitted electrons over the total heating power of a cathode. Under the assumption that power loss is by radiation only, this efficiency is calculated theoretically and its optimal value determined. Theoretical results are compared with practical values, and hints are given pointing to obtaining a, better efficiency.
