首次使用重离子束探针在中性束加热托卡马克放电中测量了等离子体电势。这些电势的径向分布针对共注入、反向注入和平衡注入，以及仅具有欧姆加热的等离子体。人们发现它们非常依赖于等离子体电流的旋转方向。还发现它们在质量上与使用测量的环形旋转速度从径向动量平衡推断的结果一致。
Plasma potentials have been measured for the first time in neutral-beam-heated tokamak discharges, with a heavy-ion beam probe. Radial profiles of these potentials are presented for coinjection, counter injection, and balanced injection, and for plasmas having only Ohmic heating. They are found to be very dependent on the direction of rotation with respect to the plasma current. They are also found qualitatively consistent with those inferred from radial momentum balance with use of the measured toroidal rotation velocity.
