(a) Different components of power versus squared minor radius for modified fictitious plasma ignition model with w = 0.7 (see Eq. (17)) profile with A = 3, and κ = 5; (b) total sum of power input, power loss, and net power. By comparing with Fig. 5, we see that the fusion power input is now the same as the Ohmic power input, and less peaked than the Bremsstrahlung or the ion loss. Also the net power is not peaked in the center but in the mid-range of plasma radius. At this time, the edge pedestal leads to a reduced required B_T.
