Abstract

Referring to a Tokamak and assuming that all plasma parameters but the magnetic field are constant in the resonant region, we can write the ratio T-r/T-O, where T-r is the effective temperature of the radiation escaping from the plasma, as a function of the three parameters T-O, n-1T-1/n-0T-0 = T-1/T-0, where T-j is the optical depth. The effective radiation temperature turns out to be different for oblique and for perpendicular propagation, this is due to "shadow" effects by the different components. For oblique propagation the shadow effects are symmetrical and the radiation temperature turns out to be the same on both sides of propagation. Another possible deviation from the Maxwellian distribution in a magnetically confined high temperature plasma is the temperature anisotropy. To show the effects due to the anisotropy we compare different cases with the same electron temperature T and different values of the anisotropy parameter R=T-11/T-perpendicular.
