Abstract

High-average power, short wavelength free-electron lasers (FELs) driven by RF accelerators require electron sources that are capable of producing beams that have both high brightness and high average current. In this paper we consider the electron source requirements for a putative 1 MW average power FEL operating at 1 micrometers wavelength. We examine the critical issues associated with developing an electron source suitable for such a device.
