A thermal barrier plasma potential structure in a three-cell axisymmetric tandem mirror has been produced using only the ion cyclotron range of frequencies (ICRF), with a central cell density of up to 1013 cm−3 and a central cell ion temperature of approximately 40 eV. Thermal barrier like potential dips occurred in the region of a magnetic field gradient, at a magnetic beach of a slow wave launched in the end cell. The barrier formation is a result of a combination of radiofrequency trapping, radiofrequency enhanced potentials and μ∇B forces. The barrier pumping is consistent with μ∇B forces and θ × drifts.

タンデムミラー型装置において、中心セル密度が最大10¹³ cm⁻³、中心セルイオン温度が約40 eVの条件下で、イオンサイクロトロン周波数帯(ICRF)のみを用いて、3セル軸対称タンデムミラーにおける熱障壁ポテンシャル構造を生成した。熱障壁様のポテンシャルの窪みは、端部セルにおいて遅波が励起される磁気ビーチの磁場勾配領域で発生した。障壁の形成は、高周波捕捉、高周波によるポテンシャル増強、およびμ∇B力の組み合わせによるものである。障壁のポンピングは、μ∇B力およびθ×ドリフトと整合的である。
