    "abstract": "Various methods have been proposed to condition an electron beam in order to\nreduce its emittance effect and to improve the short-wavelength free electron\nlaser (FEL) performance. In this paper, we show that beam conditioning does not\nresult in a complete elimination of the emittance effect in an\nalternating-gradient focusing FEL undulator. Using a one-dimensional model and\na three-dimensional simulation code, we derive a criteria for the emittance\nlimitation of a perfectly conditioned beam that depends on the focusing\nstructure.",
