A modelling study of the ITER divertor is done using the B2-Eirene code package with full multi-species impurity treatment and volumetric recombination of deuterium ions. A virtual target regime is identified, for which strong recombination and ionization form a double layer which acts like a target surface inside the divertor plasma. The power loads, erosion, and helium removal seem to be within the acceptable range for the ITER design, making this regime, together with operational points close to it, a reasonable starting point for the optimization of the ITER divertor.
