Several methods have been proposed in the literature to improve Free ElectronLaser output by transforming the electron phase-space before entering the FELinteraction region. By utilising `beam by design' with novel undulators andother beam changing elements, the operating capability of FELs may be furtherusefully extended. This paper introduces two new such methods to improve outputfrom electron pulses with large energy spreads and the results of simulationsof these methods in the 1D limit are presented. Both methods predict orders ofmagnitude improvements to output radiation powers.
