Abstract : Development and evaluation of a spatial and temporal determination diagnostic for X‐ray free‐electron lasers. Abstract : A compact and robust diagnostic to determine spatial and temporal overlap between X‐ray free‐electron laser and optical laser pulses was developed and evaluated using monochromatic X‐rays from the Linac Coherent Light Source. It was used to determine temporal overlap with a resolution of ∼10 fs, despite the large pulse energy fluctuations of the monochromatic X‐ray pulses, and covers a wide optical wavelength range from ultraviolet to near‐infrared with a single configuration.
