The ability to generate small transverse emittance is perhaps the main limiting factor for the performance of high-gain x-rays free-electron lasers (FELs). Noting that beams from an rf photocathode gun can have energy spread much smaller than required for efficient FEL interaction, we present a method to produce normalized transverse emittance at or below about 0.1 µm, which will lead to a significantly shorter length undulator as well as a lower electron beam energy for an x-ray FEL project.doi:10.1103/physrevstab.9.100702 fatcat:zqh7eljptbdx5botkbw7wwrakm
