Abstract

An electron beam generated by a GaAs photocathode, activated in negative electron affinity conditions, was studied under two different accelerating regimes. The energy spread of the beam, after an adiabatic acceleration is lower than after a fast acceleration. For the first time a longitudinal plasma parameter greater than one has been obtained for an electron beam.
