A cross-correlator-based timing tool for FemtoMAX
Published 2025-07-01“…In this case, one of the beams is a relatively weak diagnostic beam of visible light from a bending magnet at FemtoMAX (106 photons pulse−1 in a 0.2 mm high and 5 mm wide beam) while the other is a relatively intense laser beam (200 µJ pulse−1) derived from the same laser that is used to pump the sample in pump/probe experiments. This enables online monitoring of the relative timing of a linear accelerator-based, short-pulse, hard X-ray source and a synchronized visible laser. …”
