High power ICRH and NB heating results in TEXTOR
Auxiliary heating of TEXTOR is carried out by co- and counter-beam injection and ICRH heating. The main characteristics of each of these heating methods and of a combination thereof are compared and discussed. NBI-co produces a hot ion mode, characterised by a large energy anisotropy, by a large non-inductively driven toroidal current and by the stabilisation of the sawteeth, due to the hot ion tail. These effects are enhanced significantly when ICRH is added to NBI-co. The neutron yield is also increased by the addition of ICRH. Peak electron and ion temperatures around 3 keV are obtained and 70% of the total current is non-inductively driven. A large excess of the total energy content with respect to the L-mode scaling predictions is obtained with the combinations NBI-co and ICRH or NBI-co and NBI-counter.
