abstract = {The advent of x-ray free electron lasers has extended the
unique capabilities of resonant x-ray spectroscopy
techniques to ultrafast time scales. Here, we report on a
novel experimental method that allows retrieving with a
single x-ray pulse the time evolution of an ultrafast
process, not only at a few discrete time delays, but
continuously over an extended time window. We used a single
x-ray pulse to resolve the laser-induced ultrafast
demagnetisation dynamics in a thin cobalt film over a time
window of about 1.6 ps with an excellent signal to noise
ratio. From one representative single shot measurement we
extract a spin relaxation time of (130 ± 30) fs with an
average value, based on 193 single shot events of
(113 ± 20) fs. These results are limited by the
achieved experimental time resolution of 120 fs, and both
values are in excellent agreement with previous results and
theoretical modelling. More generally, this new experimental
approach to ultrafast x-ray spectroscopy paves the way to
the study of non-repetitive processes that cannot be
investigated using traditional repetitive pump-probe
schemes.},
