Description
High-gradient photocathode electron guns, serving as electron sources for advanced linear light sources, have been fully validated to enhance the overall performance of the system. As cryogenic electron guns emerge as the future trend for ultra-compact electron sources, the extremely high electric fields within the cavity induce significantly stronger dark currents. This paper simulates this effect and proposes preliminary methods for suppressing such dark currents.
