An understanding of the plasma edge and divertor is essential for predicting the performance of next-step machines such as ITER. Transport codes used to study the divertor behaviour [1] employ atomic physics data in two applications. The first is to predict the power radiated by the fuel and impurity atoms, which is carried out as a post-processing option, while the second use is in calculating the atomic power loss term. This forms part of the transport calculations and in D fuelled simulations it has been shown that the simulated temperatures are sensitive to this term [2]. A new He II (He+) atomic database [3,4] is used to check the application of the atomic data in the EDGE2D code.
