abstract = {Pump-probe methods are a ubiquitous tool in the field of
ultrafast dynamic measurements. In recent years, x-ray
free-electron laser experi- ments have gained importance due
to their ability to probe with high chemical selectivity and
at atomic length scales. Measurements are typi- cally
repeated many thousands of times to collect sufficient
statistics and vary parameters like delay or fluence,
necessitating that initial conditions are restored each
time. An alternative is presented by experiments which
measure the relevant parameters in a single shot. Here, we
present a time-to-space mapping imaging scheme that enables
us to record a range of delays and laser fluences in any
single shot of the x-ray probe. We demonstrate the use of
this scheme by mapping the ultrafast dynamics of the
optically induced insulator-to-metal Verwey transition in a
magnetite thin film, probed by soft x-ray resonant
diffraction. By extrapolating our results toward the
conditions found at x-ray free-electron lasers with higher
photon energy, we demonstrate that the presented data could
be recorded in a single shot.},
