Abstract

The lower hybrid plasma turbulence triggered by injection of hydrogen beams at the W7-AS stellarator is investigated by the collective Thomson scattering technique and by measurement of ion cyclotron emission of a plasma coloumn. Theoretical interpretation of the observations based on numerical simulations of fast ion distribution functions caused by injection of different neutral beams is proposed.
