      abstract     = {The Monte-Carlo code ERO2.0 uses full orbit resolution to
                      follow impurity particles throughout the plasma volume to
                      determine the local erosion and deposition fluxes on the
                      plasma-facing components of fusion devices in magnetic
                      confinement fusion. To have direct comparisons to other
                      transport codes (e.g., ASCOT and DIVIMP) and to accelerate
                      the code, guiding centre approximation (GCA) was implemented
                      into ERO2.0. In addition, a hybrid simulation mode for
                      ERO2.0 was developed, in which the advantages of both full
                      orbit resolution and guiding centre approximation are used.
                      In typical scenarios in this simulation mode, full orbit
                      resolution is applied exclusively near the wall region,
                      while GCA is used everywhere else along a particle's
                      trajectory. Special emphasis was put on the validation of
                      the implementation by an inner-code benchmarking to pure
                      full orbit simulations. Analysed scenarios included test
                      plasmas with simplified geometry and a realistic test case
                      corresponding to a deuterium limiter plasma used in JET
                      pulse #80319. The results of simulations performed in the
                      hybrid simulation mode are in very good agreement to
                      corresponding pure full orbit simulations, while a
                      significant code speed-up was achieved.},
