      abstract     = {The influence of plasma beta effects on the edge plasma
                      transport in the Wendelstein 7-X standard configuration is
                      studied systematically by using EMC3-EIRENE combined with a
                      3D equilibrium code named HINT. The magnetic topology
                      changes induced by plasma beta effects are significantly
                      reflected in plasma transport behaviors and heat flux
                      patterns on divertor targets. After validating the modeling
                      strategy by comparisons with experimental data, the extended
                      simulations for high performance plasmas show that the
                      threshold separatrix density for accessing the power
                      detachment is reduced in higher beta plasmas. Compared with
                      the vacuum field case, the impurity radiation distributions
                      with finite beta effects are modified in the magnetic island
                      region. The divertor heat flux is distributed more evenly
                      along the toroidal direction on the strike line at the
                      vertical target. The strike line on the horizontal target
                      moves towards the pumping gap with an increase in the plasma
                      beta. In addition, the different pressure profiles with the
                      same central beta also result in a modified heat flux
                      pattern on the divertor targets.},
