Various heating methods can be used in order to overcome the limitations of ohmic heating in low-β toroidal systems. Attention is directed to fast neutral beam injection (possibly supplemented by adiabatic compression, etc.) and to RF-heating methods based on the existence of resonances. The basic physical mechanisms involved and the most significant results obtained are briefly explained. Finally, a new heating scheme is proposed which uses kHz-frequencies and rf-coils located outside the liner.
