An electron gun for a high-power electron linac in the Japan nuclear cycle development institute (JNC) has been developed and tested. In this electron gun, two types of grid control systems (mesh grid type and double aperture grid type) were tested for their ability to deliver high average current beams. In this paper, we discuss the problems associated with each type of gun system.
