Abstract

The FOM-Institute for Plasma Physics - together with its TEC partners - is preparing the construction of Magnum-psi, a magnetized (3 T), steady-state, large area (100 cm²), high-flux (up to 10²4 H+ ions m¿²s¿¹) plasma generator. Magnum-psi is being developed to study plasma-surface interaction in conditions similar to those in the divertor of ITER and fusion reactors beyond ITER. In order to explore and develop the techniques to be applied in Magnum-psi, a pilot experiment (Pilot-psi), with a magnetic field up to 1.6 Tesla, has been constructed. One of the main design questions of Magnum-psi is how to produce the required flux. The results of Thomson Scattering and high-resolution spectroscopy on Pilot-psi plasmas presented in this paper demonstrate that a cascaded arc plasma expanding at low pressure and eventually confined by a strong magnetic field is a very good candidate to produce the required ion flux, in Pilot-psi fluxes well in excess of 10²³ m¿²s¿¹ can be reached over 1 cm².
