      abstract     = {We report on an experiment performed at the FLASH2
                      free-electron laser (FEL) aimed at producing warm dense
                      matter via soft x-ray isochoric heating. In the experiment,
                      we focus on study of the ions emitted during the soft x-ray
                      ablation process using time-of-flight electron multipliers
                      and a shifted Maxwell–Boltzmann velocity distribution
                      model. We find that most emitted ions are thermal, but that
                      some impurities chemisorbed on the target surface, such as
                      protons, are accelerated by the electrostatic field created
                      in the plasma by escaped electrons. The morphology of the
                      complex crater structure indicates the presence of several
                      ion groups with varying temperatures. We find that the ion
                      sound velocity is controlled by the ion temperature and show
                      how the ion yield depends on the FEL radiation attenuation
