      abstract     = {The prediction of the first wall deterioration and possible
                      plasma contamination by impurities is a high priority task
                      for ITER. 3D Monte-Carlo code ERO is a tool for modeling of
                      eroded impurity transport and spectroscopy in plasma devices
                      useful for experiment interpretation. Chromium (Cr) is a
                      fusion-relevant reactor wall element (e.g. component of RAFM
                      steels expected for use in DEMO). Linear plasma devices
                      including PSI-2 are effective tools for investigations of
                      plasma-surface interaction effects, allowing continuous
                      plasma operation and good control over irradiation
                      parameters. Experiments on Cr sputtering were conducted at
                      PSI-2. In these experiments the Cr erosion was measured by
                      three techniques: mass loss of the sample, quartz
                      micro-balance of deposited impurities at a distance from it
                      and optical emission spectroscopy. Experiments were modeled
                      with the 3D Monte-Carlo code ERO, previously validated by
                      application to similar experiments with tungsten (W). The
                      simulations are demonstrated to reproduce the main
                      experimental outcomes proving the quality of the sputtering
                      data used. A significant focuses of the paper is the usage
                      and validation of atomic data (resent metastable-resolved
                      dataset from ADAS) for interpretation of Cr spectroscopy.
                      Initial population of quasi-metastable state was fitted by
                      matching the modeling with the experimental line intensity
                      profiles.},
