Saturation of 0.15 nm FEL in the hard X-ray line was successfully done on 27 November 2016, followed by saturation of 15 nm FEL in the soft X-ray FEL line on February 2, 2017. For lasing of hard x-ray FEL a beam based alignment method and an undulator optimization scheme using undulator radiation spectrum analysis are fully exploited. In this paper we present the results of both schemes as well as the performance of FEL radiation. PB - JACoW CP - Geneva, Switzerland ER -
