      abstract     = {We report on synthetic helium beam emission spectroscopy
                      (BES) in fusion edge plasmas, as enabled by the 3D kinetic
                      (neutral particle) transport code EIRENE. We also review and
                      upgrade the underlying atomic helium data base, resorting to
                      the most recent version of the Goto–Fujimoto
                      collisional-radiative code and a recommended and publicly
                      exposed reference cross section data set from an
                      internationally coordinated (IAEA) evaluation activity. On
                      the example of the Wendelstein 7-X (W7-X) stellarator, we
                      use both the upgraded transport code and data base to
                      simulate the penetration of and radiation from thermal
                      helium used for BES in the island divertor region. This
                      allows to evaluate the applicability of the diagnostic in
                      different plasma backgrounds, simulated with the 3D edge
                      plasma Monte Carlo code EMC3-EIRENE, and with different
                      levels of refinement of underlying atomic data. The
                      sensitivity of the diagnostic to the atomic data set—which
                      is crucial for a quantitative determination of electron
                      density and temperature profiles—is investigated and
                      discussed, as well as the effects of p-He beam widening and
                      correlated line-of-sight integration.},
