INEX modeling of the Boeing ring optical resonator free-electron laser
Abstract
New results are presented from the integrated numerical model of the accelerator/beam transport system and ring optical resonator of the Boeing free electron laser experiment. Modifications of the electron beam transport have been included in a previously developed PARMELA model and are shown to reduce dramatically emittance growth in the 180 deg bend. The new numerically generated electron beam is used in the 3-D FEL simulation code FELEX to calculate expected laser characteristics with the ring optical resonator and the 5-m untapered THUNDER wiggler. Gain, extraction efficiency, and optical power are compared with experimental data. Performance sensitivity to optical cavity misalignments is studied.
