  Shanghai soft X-ray free-electron laser (SXFEL) started its construction in December of 2014. After years of effort, first lasing at 8.8 nm with designed cascading mode is finally achieved in 2019. The commissioning progress and recent results will be reported.

  The longitudinal phase space of the high repetition rate injector beam usually twisted and deteriorated by the space charge force. It causes the correlated energy spread and the local chirp within the beam, which could not compensated by the harmonic correction. As a consequence of this problem, one could not get ideal beam with a peak current more than kiloamperes. In this paper several approaches have been studied to relieve this effect and get the well compressed beam for the lasing.
