An external ring electrode is used to create a radial electric field that induces E x B rotation of the individual beams around a common axis. Rotation profiles with maximum speeds up to 10 km s(-1) are measured from the hydrogen atomic line shapes and confirm rotation around the ring axis. Mixing to a total beam diameter of similar to 2.5-3 cm is observed in density profiles measured with Thomson scattering near a target at 0.5 m downstream. Currents of up to 60 A were received by the ring, involving an addition power input of up to 5.4 kW to the plasma. }, year = {2011}, journal = {Plasma Physics and Controlled Fusion}, volume = {53}, number = {10}, pages = {5013}, month = {Oct}, isbn = {0741-3335}, doi = {10.1088/0741-3335/53/10/105013}, note = {ISI Document Delivery No.: 823VVTimes Cited: 0Cited Reference Count: 15}, language = {English}, }
