Abstract：
The principle and development of the thermionic cathode electron gun used as a injector of a high brightness RF linac are introduced. The numerical computation of the beam current, energy spread and emittance are given. A prototype of the gun was tested and some experiment results are reported. The paper concludes with a discussion of the existing problems and possible improvements in its performance.
