Abstract
High-gain, self-amplified spontaneous emission free-electron lasers (S ASE FEL's), with proposed operation in wavelengths extending down to x rays, require intense relativistic electron beams, which under certai n conditions can generate large diamagnetic fields. The action of thes e fields has the potential to seriously degrade FEL performance. It is shown here by both analysis and simulation that the finite size of th e electron beams diminishes this effect so that it is negligible for p roposed SASE FEL's.
