a Schematics of the GPSR method22. b Cartoon showing an evolution of beam energy chirp by the accelerating field. c Schematic view of the first bunch compressor34 section at the PAL-XFEL. Training and test datasets are measured at the screen 135,36. The lattice used for the reconstruction training process is in the dashed orange box. d Validation section. The longitudinal phase space is measured at screen 2 using S-band TCAV and spectrometer37 [e measured longitudinal phase space for BC and XLIN OFF]. Measured beam charge and reference energy for the reconstruction process are 250 pC and 260.5 MeV, respectively.
