      abstract     = {ERO2.0 is a recently developed Monte‐Carlo code for
                      modelling global erosion and redeposition in fusion devices.
                      We report here on the code's application to ITER for
                      studying the erosion of the beryllium (Be) first wall armour
                      under burning plasma steady state diverted conditions. An
                      important goal of the study is to provide synthetic signals
                      for the design of two key diagnostics: the main chamber
                      visible spectroscopy and the laser in‐vessel viewing
                      systems. The simulations are performed using toroidally
                      symmetric plasma backgrounds obtained by combining SOLPS
                      simulations extended to the wall using the
                      OSM‐EIRENE‐DIVIMP edge code package. These are then
                      further combined with a shadowing model using magnetic field
                      line tracing to provide a three‐dimensional correction for
                      the flux patterns. The resulting plasma wetted area, which
                      amounts to $∼10\%$ of the total first wall area, is in
                      excellent agreement with shadowing calculations obtained
                      with the SMITER field line tracing code. The simulations
                      reveal that the main Be erosion zones are located in regions
                      intersected by the secondary separatrix, in particular the
                      upper Be panels, which are close to the secondary X‐point.
                      For the particular high‐density Q = 10 background plasma
                      case studied here, $∼80\%$ of the eroded Be is found to
                      re‐deposit on main chamber surfaces. The rest migrates in
                      almost equal parts to the inner and outer divertor and is
                      deposited close to the strike lines.},
