Abstract : Operation of a high gain VUV/Soft X-Ray Free Electron Laser (FEL) oscillator on the Stanford X Ray Center (SXRC) storage ring is investigated. Laser energy and emittance acceptance in the high gain regime for XUV light are examined using the FEL amplifier simulation code FRED. Assuming 50% mirror reflectivity, oscillation is shown to be feasible down to 220 A with a realizable wiggler magnet placed in the 27 meter straight section of the 1 GeV SXRC ring. Laser output power and time structure are determined for a 960 A oscillator operating in both 'cw' and slow pulsed modes.
