- Abstract
Performance of Self Amplifed Spontaneous Emission (SASE) operation for an X-ray Free-Electron Laser (FEL), is optimized by Multiple Objective Evolutionary Algorithms (MOEA). Different types of hybrid planar undulators are considered to achieve 0.5 Å = FEL = 1.5 Å wavelength range. This demand is regarded as a continuous optimization problem, and hence, an evolutionary algorithm is designed to find optimal FEL performance parameters. An encoding scheme comprising of undulator period (u) and undulator gap (g) is adopted here to find optimal values for saturation power (Psat) and FEL subject to several physical constraints on u and g such as the ratio of g/u and Lsat. It is shown that MOEA gives optimal solutions for estimation of Lsat with plausible Psat values.
