Abstract: Studies a method of cathode heating using a laser for an electron gun. Practicality of the heating system; Characteristics of the laser-heated gun with a dispenser and thermionic cathodes; Efficiency of direct laser irradiation; Observation that the growth of electron beam emittance was very small in the laser heating.
