Pg. Oshea et al., SHORT-WAVELENGTH SASE USING THE PALADIN WIGGLER, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 393(1-3), 1997, pp. 129-132
We consider linac-driven SASE (Stimulated Amplification of Spontaneous
Emission) XUV/X-ray FELs using the Duke linac and the PALADIN wiggler
, SASE design studies using this equipment are described based on the
non-wiggler-averaged FEL simulation code MEDUSA. We have identified a
new Collective Compton Regime in which AC space charge is unimportant
but the DC self-fields of the beam are important.
