abstract = "We studied in detail the FEL dispersion relation for a spatially uniform electron beam, taking into account energy spread and the effects of space charge. We derived the maximum number of growing modes and the upper frequency cut-off for energy distributions satisfying a few constraints. Since the FEL dispersion relation for an infinite electron beam can be reduced to the 1D FEL dispersion relations when the radiation propagates along the undulation's axis, our analyses and findings directly are applicable to 1D FELs.",
