Abstract

A high-brightness electron source of ultrasmall emittance and high average current is one of the most important components for next-generation light sources based on an energy-recovery linac (ERL). Such a high-brightness electron source can be realized by a DC photocathode gun driven by laser pulses tailored in the temporal and spatial dimensions. We propose a novel photocathode based on a quantum cascade laser (QCL). Since the ultrafast response of photoelectron emission from QCL is compatible with the tailored laser pulses, it is a candidate electron source for ERLs.
