Abstract :
Two-dimensional argon ion velocity distribution functions in the expansion region of a helicon plasma source have been obtained by laser-induced-fluorescence tomography. Below a threshold value of the magnetic field in the expansion region, a fast ion population moving away from the source appears in addition to the nearly isotropic, slow, background, ion population.
