Abstract

A high-brightness electron source of ultra-small 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 photo-cathode gun driven by laser pulses tailored in temporal and spatial dimensions. We propose a novel photocathode based on a quantum cascade laser (QCL). Since ultrafast response of photo-electron emission from the QCL is compatible with tailored laser pulses, it is a candidate for the electron source for ERLs.
