Resistive Plasma Heating

The ohmic component of the plasma heating is given by that from the ITER 1989 Physics Design Guidelines¹

Using the resistive loop voltage for a reference profile of parabolic shape with:

$$\alpha_n \approx 0.5, \alpha_T \approx 1.0, \alpha_J \approx 1.5$$

$$\Omega_{\text{plasma}} \approx 2.15 \times 10^{-3} Z_{\text{eff}}\langle \gamma_{\text{NC}} \rangle \frac{R_0}{\kappa a^2} \frac{1}{T_{10}^{1.5}}$$

The neoclassical (avergae) resisitivity enhancement factor $\left(\langle \gamma_{\text{NC}} \rangle \right)$ is given by an empirical fit:

$$\langle \gamma_{\text{NC}} \rangle = 4.3 -0.6A$$

where $A$ is valid in the range of 2.5 - 4.0.
