A 1D imaging soft X‐ray spectrometer installed on the small quantum systems (SQS) scientific instrument of the European XFEL is described. It uses movable cylindrical constant‐line‐spacing gratings in the Rowland configuration for energy dispersion in the vertical plane, and Wolter optics for simultaneous 1D imaging of the source in the horizontal plane. The soft X‐ray fluorescence spectro‐imaging capability will be exploited in pump–probe measurements and in investigations of propagation effects and other nonlinear phenomena. A 1D imaging soft X‐ray spectrometer, installed and commissioned on the SQS instrument of the European XFEL, is described.
