Study and Modelling of the Neutron Emission from High Density ELMy-H-mode Discharges with and without Impurity Seeding

ELMy H-mode is the reference mode of operation for ITER. Confinement properties of this mode are intensively studied under various scenarios. Scenarios using impurity seeding and plasma shaping allow to reach simultaneously high confinement at high density while achieving good plasma edge properties. In this paper, we investigate the neutron emission from high density ELMy-H mode discharges, we apply a model to compare the prediction with measurements in order to understand the neutron production. Finally, we look at specific effects on neutron behavior which may arise from impurity injection or in highly shaped plasmas.
