In this work we describe the heating results in the LH frequency range (f = 2.45 GHz,Prf lt=250 kW, Ps lt= 6 kW/cm2) both in the electron and ion regimes. Efficient electron heating was observed for n lt= 5.10 13 cm-3. Increases of the peak electron temperature up to700 eV were measured. At higher densities the interaction with electrons disappears. In theion regime fast neutral tails and neutron enhancement were observed. The influence of plasma boundary conditions on the penetration of the wave is demonstrated. The principal physical problems are pointed out and some possible conclusions are given.

本論文では、周波数範囲LH(f = 2.45 GHz、Prf ≤ 250 kW、Ps ≤ 6 kW/cm²)における加熱結果を、電子領域とイオン領域の両方について報告する。電子加熱は、n ≤ 5.10¹³ cm⁻³ において効率的に観測された。ピーク電子温度は700 eVまで上昇した。より高密度では、電子との相互作用は消失する。イオン領域では、高速中性粒子のテールと中性子増強が観測された。プラズマ境界条件が波動の浸透に及ぼす影響が実証された。主要な物理的課題が指摘され、いくつかの可能な結論が提示される。
