Description
Understanding the interaction of suprathermal ions with plasmas is a crucial step in the quest for nuclear fusion, because these ions are required to heat the main plasma during ignition and losing them can damage the vessel walls. Basic plasma experiments like TORPEX have made important contributions in this area through studies of suprathermal lithium ion transport in a simple magnetic configuration.
Recently, a more complex magnetic configuration (X-point) has been developed and extensively characterized. We present here two X-point scenarios that have been selected for new suprathermal ion transport studies. Simulations and experiments have been performed in these conditions and are presented and compared.
