We are conducting research on a thermionic electron gun with high average current for a superconducting electron linac which will be used for wastewater purification and RI production. The electron gun will generate the pulsed beam by using a DC high voltage and driving the grid at high speed. The current dependence of emittance is investigated numerically based on the existing electron gun setup. We will now proceed to optimize and improve the geometry and configuration of the injector components such as focusing magnets and bunching cavities to inject a high current beam into the superconducting RF cavities. In order to evaluate the actual beam produced by the electron gun, a test stand for the electron gun is currently being constructed. In this presentation, we will present the results of the measurement experiments.
