Neutral beam injection (NBI-co and NBI-counter), ICRH and their combinations have been compared on TEXTOR for what concerns the heating and their effect on the energy anisotropy and the confinement. In most of the cases, stationary heated plasma conditions have been obtained with boronized wall. The main results are: (i) Production of a hot ion mode with NBI-co. It is characterized by a large energy anisotropy, by a large noninductively driven toroidal current and by the stabilization of the sawteeth (of the monster type) due to the hot ion tail. (ii) Significant enhancement of these effects when ICRH is added to NBI-co. The neutron yield is also increased by the addition of ICRH. Peak electron and ion temperature around 3 keV have been obtained and 70% of the total current has been non inductively driven. (iii) Large excess of the total energy content (up to 2.3) with respect to the L-mode scaling predictions has been obtained with the combinations NBI-co+ICRH or NBI-co+NBI-counter. (iv) Up to 6 MW of additional power has been coupled to the plasma leading to beta p=1.5 and beta t equal to 70% of the Troyon limit.
中性束注入(NBI-co和NBI-counter)、ICRH及其组合已在TEXTOR上就加热及其对能量各向异性和约束的影响进行了比较。在大多数情况下,通过硼化壁获得了稳态加热等离子体。主要结果如下:(i)利用NBI-co产生了热离子模式,其特征是大的能量各向异性、大的非感应驱动环向电流以及由热离子尾部引起的锯齿 stabilization(巨锯齿类型)。(ii)当ICRH叠加到NBI-co上时,这些效应显著增强。中子产额也因ICRH的加入而增加。获得了约3 keV的电子和离子峰值温度,且总电流的70%为非感应驱动。(iii)对于NBI-co+ICRH或NBI-co+NBI-counter组合,总能量约束相对于L模定标律的超出量高达2.3倍。(iv)向等离子体耦合的附加功率高达6 MW,导致β_p=1.5,且β_t达到Troyon极限的70%。
