It is found that the ion beam is only observed below 3mTorr and only when the discharge is operated in inductive mode. The geometrical expansion of the plasma induces density and potential gradients leading to the ion beam formation. The ion beam energy increases with decreasing source tube radius. The results show that ion beam formation can be achieved by geometrical expansion alone and that the ion beam energy depends on the ratio of the cross-sectional area of the source and expansion region.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380306906081903754","@type":"Researcher","foaf:name":[{"@value":"C.
