Electron-cyclotron heating in NET using the ordinary mode at down- shifted frequency
A new scenario of electron-cyclotron heating of a tokamak reactor is proposed, which makes use of the low-field-side normally injected ordinary mode at down-shifted frequency. Using the NET parameters, it is shown that the ordinary mode is strongly damped in the central plasma region for an electron temperature in excess of a few keV after reflection by an obliquely orientated mirror located opposite the launching position. This scheme makes the heating of NET possible by using wave sources at frequencies as low as 100-125 GHz for a magnetic field of 6T, i.e. an electron gyrofrequency of 168 GHz.
